Pluto gains a fourth moon, but what should it be named?

Pluto may have been demoted to a dwarf planet in 2006, but that hasn’t stopped astronomers from studying this intriguing plutoid. NASA recently announced the discovery of a fourth moon, be it a “mini-moon,” circling the former planet. Dubbed “P4” for the time being, the hunt is on for an appropriate name.

The practice of naming planets after gods and goddesses can be traced back to the Babylonians, but it is the naming conventions of the Romans that we continue to refer to today. The International Astronomical Union has established a set of guidelines for planetary nomenclature that is monitored by a group of scientists.

Pluto’s name comes from a lovely and unlikely source. Fueled by a passion for classical mythology and astronomy, Venetia Burney, an eleven-year-old schoolgirl from Oxford, England, proposed the name Pluto to her grandfather (a librarian at the Bodleian Library at Oxford University) who in turn passed it on to astronomers at the Lowell Observatory. From a list of three prospective names, Venetia’s suggestion won out. For her achievement, Venetia’s grandfather rewarded her with five pounds.

Of the now four moons circling Pluto, Charon is the largest. The name is a derivation of the Greek Kharon – the ferryman of the dead over the river Styx. Charon is closely associated with the god Hades, whom the Romans link with Pluto.

The two remaining moons, Nix and Hydra are named in part for their initials NH, a reference to the New Horizons robotic spacecraft mission; or perhaps the names suggest the watchful eye the two keep over Pluto.

Nix is derived from the Greek Nyx, the goddess of darkness and night, and mother of Charon. The alternate spelling (replacing the y with an i) is to avoid confusion with the asteroid called 3908 Nyx.

Hydra is named for the nine-headed Lernaean beast who battled, and was eventually slain by, Hercules in Greek mythology.

In keeping with tradition, from what figure of Greek mythology should this newly discovered satellite be named? Offer your suggestion below.

Artist’s whimsical ‘Pig’ images on display

The Columbian (Vancouver, WA) January 26, 2006 | MATT WASTRADOWSKI Columbian staff writer In commercial artist Trip Gruver’s world, pigs fly and horses don life jackets to take a swim.

“Pigs Can Fly” and “Horses Can Float” are two series of Gruver’s colorful, digitally altered photographs. The Vancouver-based artist melds public domain images and cartoony animals to create what he calls “super-reality,” or natural-looking blends of extremely different elements. go to web site public domain images

Both series are on display at the North Bank Gallery, 1005 Main St., through Saturday. Artist Carrie White, who is showing her collection of paintings entitled “Beautiful,” produced and curated the show. White says Gruver’s vibrant images complement her colorful paintings. The North Bank Gallery is a cooperative run by artists.

“Pigs Can Fly” was born after one of Gruver’s commercial projects in Kuala Lumpur fell through in early 1999. Gruver created one of the images as a joke, suggesting that “perhaps we’ll do this job when pigs can fly.” His youngest children, now ages 10, 8 and 7, enjoyed the project so much, Gruver started “Horses Can Float” in 2003. Each series includes 12 images, which Gruver hopes to publish as a series of children’s books after the exhibit ends. Upcoming image sets include “Sheep Can Slide,” “Snakes Can Stand” and “Frogs Can Run.” Having his work on display is nothing new for Gruver. He says he co-produced and directed animated shorts for Sesame Street between 1982 and 1984, and was involved with commercials for such brands as Charmin, Huggies and Capri Sun.

Gruver’s most recognizable work was a series of about 20 “Michelin Baby” television commercials, which he says he designed and directed for Michelin Tires between 1990 and 1996. The half- film and half-animated spots became a hit and are now a part of pop culture. White says of the commercials’ success, “Moms really saw those tires as being safe for their babies.” Whether he’s creating Michelin babies, flying pigs or floating horses, Gruver says he doesn’t “need to change the world,” but his goals are simple: He just wants to make people smile. here public domain images

If you go What: Exhibit of Trip Gruver’s digitally altered photos including “Pigs Can Fly” and “Horses Can Float.” When: 11:30 a.m.-4:30 p.m. daily through Saturday.

Cost: Free.

    i think it should be named for Thanatos the god of death because when people think of Pluto they think of the underworld which makes them think of death. plus he is Nix’s son. i really don’t want Persephone because she has nothing to do with Pluto except she is his wife and she didn’t even choose that. she’s the goddess of spring for goodness sake.

    oh and when i said i want it to be named Thanatos i mean Thanatos not his Roman equivalent Mors. i hate that everyone knows the Roman gods and not the Greek ones. just because Rome was better at conquering lands and being an empire doesn’t mean they’re better than Greece. actually the Greeks were better at all the other stuff like voting and managing not to kill all their kings. they were also better at religion. they thought of all the major deities and the Romans just stole it from them. they also thought of most of the legends and myths which the Romans just copied. sure the Romans had way more gods but that’s just because they copied all the Greek ones.

    whether you agree or disagree with me, please reply. thanks :)

    • Fae -  March 16, 2015 - 11:53 pm

      Your reasoning is confusing in regards to not wanting Persephone… if you’ve ever read any myth concerning her in detail, it is very clear that she chooses Hades just as much as he initially chose her. She becomes a full-blooded Queen of Hell, and is actually much more terrifying and intimidating than her husband. In the old age, ancient Greeks were actually forbidden from idly speaking her name, whereas with the other gods it’s was much more relaxed.

  2. Resuna -  February 13, 2013 - 8:50 am

    Mickey and Goofy, as per Robert Anton Wilson.

    Or start over and name them Cocytus, Caïna, Antenora, Ptolemea, Judecca, as per Larry Niven.

  3. Mythology Know-It-All -  November 27, 2012 - 3:09 pm

    I believe Pluto’s fourth moon should be named for:

    Cerberus- the 3-headed guard dog of the underworld
    Persephone – the beautiful but ill-fated wife of Hades
    Proserpina – the Roman form of Persephone
    Thanatos – the god and personification of death
    Mors – the Roman form of Thanatos
    Tartarus – the deepest, darkest part of the Underworld. Where invincible beings are imprisoned.
    Erebos – Greek god of darkness
    Styx – the river that separates the realm of the living from the realm of the deceased. Styx actually means hate. The gods would use the water from the Styx to tell if someone, mortal or immortal, was telling the truth.
    Acheron – the river in the Underworld that is the river of woe.
    Cocytus – the river of lamentation. If dead souls were not buried properly, they would drift across Cocytus’s banks for all of eternity.
    Lethe – the river of forgetfulness, in which dead souls bathe in to forget who they were during life.
    Phlegethon – the river of Hades’s fire
    Hecate – Greek goddess of darkness. It is said that she roams in darkness with her dogs and represents the terrors of the night. She is also goddess of magic and sorcery.
    Trivia – Roman form of Hecate

    There are many more options, but I don’t have time to type them all.

  4. Li Yang -  November 16, 2012 - 4:54 pm

    to all who chose ceberus that idea had just been taken for an asteroid I choose Thanantos the guardian of the doors of death

  5. awsomespacegeek -  July 16, 2012 - 11:21 am

    It think it should be called Boreas, Greek god of the north wind. Its easy to remember and it sounds cool. Its cold there, so i searched Roman god of cold and i got this (no roman god of cold due to Rome, Italy being warm :P)

    • Aidan Clark -  November 22, 2014 - 6:54 pm

      There was a Roman form of Boreas. The problem is: you searched for Roman god of cold. Boreas happens he Greek god of the north wind (which is cold). Boreas’s Roman form is Aquilon.

    @ Demosthenes (or should I say, nothing or noone or whatever):
    “In keeping with tradition, from what figure of Greek mythology should this newly discovered satellite be named? Offer your suggestion below.” DUH!

  8. Demosthenes -  May 19, 2012 - 2:56 pm

    Why does everybody all say they vote for one thing or another? The people making the actual decision don’t care what you think. And why do we have to name everything we see? It’ll just cause unneeded sadness that the majority of people didn’t get what they wanted. We don’t have the right to name this moon, especially if we’ve only discovered it this late. And I agree with ME!!!!!!! in that we should leave it at nothing. Everyone could call it what they believed was the right name. And there isn’t really a “right” name. Names don’t suit anything perfectly; the only truly fitting name is no name at all. Anyway, does the name of a moon some 10 billion miles away really mean this much to you. IT DOESN’T MATTER what some ball of ice out in space is called, so why spend your time arguing about this. There’s no right decision, so don’t make a decision. Put your time into something productive, like learning to capitalize the “I” in your posts.

    • Archaeologist/Explorer -  May 28, 2014 - 6:17 pm

      i really think this is an interesting post. i don’t totally agree with u but i think u deserved to be told that only a smart person can right something like this

  9. bleue -  May 18, 2012 - 7:02 pm

    @ Emma on July 25, 2011 at 2:52 am
    Phobos and Deimos (Panic and Fear)are already the moons of Mars.

    to all who suggested Cerberus…
    Yes while it’s true that that three-headed dog is associated with Pluto, it is also true that it guarded the entrance to the underworld and it will be unfitting if the guardian will be “far” from what it’s guarding.

    LETHE would be a more suitable name since it’s the river of forgetfulness. This new moon almost was forgotten.

  10. sam i am -  May 14, 2012 - 9:15 am

    For my last commet, Titancom is pronounced t-I-an-come

    I have to agree on “Cerberus”

  14. ana -  March 1, 2012 - 6:35 am

    persephone is already taken and so is pluto.

  15. ana -  March 1, 2012 - 6:32 am

    Eos the greek god of the moon

  16. Caleb Roberts -  February 23, 2012 - 9:53 am

    The following names of moons are already in use:

    Adrastea, Amalthea, Ananke, Ariel, Belinda, Bianca, Callisto, Calypso, Carme, Charon, Cordelia, Cressida, Deimos, Desdemona, Despina, Dione, Elara, Enceladus, Epimetheus, Europa, Galatea, Ganymede, Helena, Himilia, Hyperion, Iapetus, Io, Janus, Juliet, Larissa, Leda, Lysithia, Metis, Mimas, Miranda, Naiad, Nereid, Oberon, Ophelia, Pasiphae, Phobos, Phoebe, Portia, Proteus, Puck, Rhea, Rosalind, Sinope, Telesto, Tethys, Thalassa, Thebe, Titan, Triton, and Umbriel.

  17. adem uzel -  January 29, 2012 - 3:09 pm

    cerberus for such an small moon that is a long word wont suit it especially when theres nyx and hydra which are bigger moons

  18. Phlondar -  January 17, 2012 - 10:19 am

    What about Phlondar

  19. jewel -  January 5, 2012 - 7:28 am

    I think it should be Athina.

  20. April -  November 21, 2011 - 3:55 pm

    I believe it should be called abuto because it means i have hidden and the moon has been hidden so it fits. Also great job NASA for finding this new moon! :)

  21. kara -  November 17, 2011 - 4:12 pm

    Cerberus (3 headed dog that guarded the underworld) or Styx (name of a river in the underworld)

  22. Richard -  October 17, 2011 - 8:05 pm

    I believe it should be named either Janus, the god of beginnings, ends, time, decisions and doorways, Hades, god of the underworld or Cerebus, gatekeeper of the underworld

  23. Allan -  October 10, 2011 - 3:20 am

    I suggest calling it Styx, where the first two letters S and T are in honor of Alan Stern, founder of the Pluto Underground and leader of the New Horizons mission. Because Styx and Sterns can break our Browns.

  24. Kodamaface -  October 7, 2011 - 4:31 pm

    I vote for Cerberus. I don’t think a -350 degrees frozen up moon should be named after Persephone, the goddess of spring. and pokemon? seriously? people 200 years from now will look back and facepalm at the stupidity of their ancestors.

  25. Ryan -  October 6, 2011 - 7:53 pm

    Name it: Ryan

  26. Miodrag K -  October 6, 2011 - 4:11 pm

    If it had not been named yet, then — for sure — Radamanthys, one of the judges in the Hades.

  27. franko -  September 2, 2011 - 4:35 am

    Lets use Disney mythology.

    Name it Mickey.

  28. Kimmy -  August 29, 2011 - 9:21 pm

    They should call it Hypnos, the Greek god of sleep, or Persephone, Hades’ wife. Hypnose because hes the god of sleep, I don’t really know how else to explain that. Persephone, well because she’s Hades’ wife. It could also be named Tartarus, where Zeus trapped the titains. But, I’d go with Persephone.

  29. qweqwe -  August 26, 2011 - 11:54 am

    name it emboar!
    or raichu

  30. Parker -  August 24, 2011 - 4:21 pm

    The name should obvious; Astraeus, Titan of Dusk

  31. James -  August 23, 2011 - 2:14 pm

  42. Simon Ebo -  August 14, 2011 - 4:34 pm

    I think it should be named Hades, because that name is closely linked with Charon.

  43. Laura -  August 10, 2011 - 1:07 pm

    i would name it morpheus after the god of dreams… and the matrix

  44. Opinions_R_Like -  August 5, 2011 - 8:57 pm

    Mickey. As in Mouse. Pluto and Mickey.

    Or, just “Ralph.” Ralph is an unlikely name for a planet which makes it the perfect choice. So does “Bob.”

    Jollibee . . . .

  46. inciya rakos -  August 2, 2011 - 11:33 am

  48. random_Em -  August 1, 2011 - 1:09 pm

    Hypnos. I saw someone else say it and it just seemed to fit so well. From wikipedia : “In Greek mythology, Hypnos (“sleep”) was the personification of sleep; the Roman equivalent was known as Somnus. His twin was Thánatos (“death”); their mother was the primordial goddess Nyx (“night”). His palace was a dark cave where the sun never shines.”

    Proserpina or Persephone, same thing but different cultures.

  51. yayRay Shell :) -  July 30, 2011 - 9:52 am

    I think it would relate if it were named Cerberus, like what Bill Watson (the first comment) said.

  52. Lando Calrissian -  July 30, 2011 - 9:51 am

    It should be Styx, but after the band, not the river.

  53. raspberry -  July 29, 2011 - 9:39 pm

    Lethe for sure. Super appropriate

  54. Jarrek Holmes -  July 29, 2011 - 6:04 pm

    I mean moon, same difference

  55. Jarrek Holmes -  July 29, 2011 - 1:53 pm

    The name should be Stygian, a greek word for gloomy or such and is related to the river styx, appropriate and fitting, also because it keeps with tradition and would be outside the box and fitting for a 4th planet. This is because it also is within the Japanese mythology that the fourth number is unlucky somewhat like stygian. A mix between two mythology, good name.

  56. Astronomy,co.uk -  July 29, 2011 - 12:22 pm

    We shall name it Sibyl…from greek mythology Cumaean Sibyl

  59. Hana -  July 29, 2011 - 3:45 am

    If not, Some greek names shall fit in well..
    (It should be named after me..!!! XP(LOL)…My name is Basil..XD)

  60. Robin Lopez -  July 29, 2011 - 2:05 am

    You should name it Saix, Zexion, or Nephormulas idk

  61. Tom -  July 28, 2011 - 9:38 pm

    How about “Pluquatroluna”

  62. Dawn Falls -  July 28, 2011 - 9:09 pm

    I believe the new moon should be named Hecate (Hekate).

  63. Ellara -  July 28, 2011 - 8:36 pm

    hades which means “unseen” as this moon was for so long
    or just Selene meaning “moon”

  64. Joe Sobel -  July 28, 2011 - 8:08 pm

    Let me offer the name: ALERA. It means just enough to be noticeable!

  72. Madelin -  July 28, 2011 - 4:52 pm

    I think for once, the tradition of naming things in the universe after things in mythology should be broken just one time. Why not name Pluto’s fourth moon Atlantis, after NASA’s last mission launch of Atlantis and its retirement. After all, Atlantis was launched by NASA and NASA did discover this moon.

  79. Kevin Zhu -  July 28, 2011 - 3:48 pm

    @kyle how about both? LOL

  80. Molly -  July 28, 2011 - 3:46 pm

    I think the new moon should be named Selene, after the Greek Goddess of the moon.

    It adds a happy air to the planet’s neighborhood because Selene’s love, Endymion, evaded death by being granted eternal life, symbolizing that death doesn’t always win. Even if Endymion wasn’t eternally youthful so he shriveled up.

  81. Fonda Zenofon -  July 28, 2011 - 3:35 pm

    The fourth moon of Pluto could be called – Tesera – which is the Greek word for the number 4. Tesera sounds Terestial, which I think is appropriate.

  82. Cayenne -  July 28, 2011 - 2:41 pm

    Boo, Chione is an asteroid. Persephone, Pandora and Proserpina also taken by asteroids. Pandora is also a moon of Saturn.

    Maybe “Momus”, god of satire, mirth and mockery. Son of Nyx (Nix – so would be sibling to Charon). Charon, Nix, Hydra and Momus.

  96. Silverius Materi -  July 28, 2011 - 12:10 pm

    I believe Erebus might be an appropriate name. He is the god of shadows, brother and, in most myths, male consort to Nyx. Keep all the names familial for the moons. Father, Mother and Son.

    Name for the fourth moon around the “planet” Pluto: Pandora. What will Pandora reveal? This moon was in hiding for about 71 years since the discovery of Pluto, and yet Pluto still has not completed one orbit around the sun.

  109. alexandra -  July 28, 2011 - 10:18 am

    its should be Enma, also known as Yama, is a deity from Buddhist and Hindu tradition who judges the dead with either reward or punishment in Jigoku (a world in the afterlife usually referred to in English as the Japanese “Hell”).
    Or, Cerberus the multiheaded dog which guards the gates of The Underworld.

  110. Nicole -  July 28, 2011 - 10:15 am

    My vote is for “Apollymi”, the greek goddess of destruction. Also referred to as the “Destroyer”.

  111. Pete Byle -  July 28, 2011 - 10:14 am

    @ Maria Mediarito …….. I vote for your suggestion. I think it can’t be anything but LETHE. I like to think that naming it in respect to mythology is the way to go.

  112. Ice -  July 28, 2011 - 9:52 am

    Persephone in modern English—also called Kore

  113. Sujin -  July 28, 2011 - 9:45 am

    I really think it should be named Persephone

  114. Michael Creamer -  July 28, 2011 - 9:37 am

    A fitting name would be Perseus for the newly discovered moon

  115. coltrain -  July 28, 2011 - 9:34 am

    I think it should be named,

    “I used to be a moon of a planet, but now I’ve been reduced by
    some narcissistic so-called scientists to being a moon of a mere
    rock, pretentiously renamed a newfangled moniker called a ‘plutoid’ .”

    I’m just sayin’…

  116. Kero -  July 28, 2011 - 9:05 am

    Totally Erebus: Spirit of darkness; son of Chaos. He is a Roman god.

  117. Dee -  July 28, 2011 - 8:32 am

    My suggested name would be Demeter. Life after death. That to me sound like the right name.

  118. Leo V -  July 28, 2011 - 8:29 am

    I think Cerberus is too big a name to call a “mini-moon”. And Lethe and Persephone are too beautiful. I like Erebos though. Isn’t he Nyx’s husband? I also think Ixion is nice. Both are not that well known, in other words, small names. Small names for a small moon.

  119. Heather -  July 28, 2011 - 8:05 am

    I agree with Binaya, it should be Styx after the river Styx. What a great word!

  120. Mark -  July 28, 2011 - 7:36 am

    Definitely Mickey. Leave the Roman shit in the past. How long are we going to go on scrambling around for Roman names? Pathetic! Lighten up people and call it Mickey! :)

  121. Marlene Dilla -  July 28, 2011 - 7:26 am

    The best name is Cerberus, for sure

  122. Cecilia -  July 28, 2011 - 7:14 am

    I think it should be named Artemis.

    Artemis was the daughter of Zeus and Leto. She was Apollo’s twin sister.

    Artemis was nearly always cold (it would be cold to be that far from the sun!). The only thing Artemis loved besides her family were her floppy-eared dogs.

    Artemis was the goddess of the hunt and the goddess of the moon.

  123. Hana -  July 28, 2011 - 6:30 am


  124. Heracles -  July 28, 2011 - 5:47 am

    Heracles is Greek. Hercules is Roman. Get your mythology straight.

  125. Mateus -  July 28, 2011 - 5:31 am

    Let’s name it Fifi, Minnie’s pet and Pluto’s first girlfriend. What about a bit of fun?

  126. Tom -  July 28, 2011 - 5:03 am

    I like “The Moon With No Name”, said with a Scottish accent, as it is theatrical, implies mysteriousness (is “mysteriousness” even a word?), and is my idea.
    But it’s also literary or cinematic in origin, I think, so probably not on theme with the existing naming convention for planets and moons.
    It’s also five words, which doesn’t fit well with the single-word convention, either. But as we’re running out of cool sounding, mythical, single words anyway, why not take the opportunity to break out into a new, multi-word-celestial-body-naming era?

    Otherwise, Maria Mediarito’s idea of “Lethe” sounds good, if her justification is correct.

    “Cerberus” is already overused (see “running out of cool-sounding, mythical, single words” argument, above), but a good fit to the context.

    “Cerebrus” would be a great way to get everyone confused and tongue-tied, mixing it up with “Cerberus”.

    Anyone know how I could waste another five minutes?

  127. DEBORAH -  July 28, 2011 - 4:54 am

    Maybe what ever the Latin or Greek word is for PEACE
    May bring some hope to our universe……

  128. Derek -  July 28, 2011 - 4:47 am

    I think Posidon, brother of Zeus, God of the sea, where fishes live.
    Most fish have fins.
    This moon has just slipped into our knowledge. One can slip someone a Micky fin and Mickey was the mouse that owned Pluto.

    Just a thought……

  129. jdsosa -  July 28, 2011 - 4:22 am

    know 1 knows what is the name of that moon only God knows

  130. jdsosa -  July 28, 2011 - 4:21 am

    know one knows what should the name of that 4th moon

  131. Oscar -  July 28, 2011 - 4:03 am

    I think the 4th moon of Pluto should be named Cerberus because he was the 3 headed dog that guarded the gates to the Underworld. Its like Pluto is the Underworld and the new moon looks like it is guarding the planet.
    Oscar(11 years old)
    P.S.SPretty please with cherry on top.

  132. cerebus -  July 28, 2011 - 2:50 am


  133. Henry M Harris -  July 28, 2011 - 2:40 am

    The fourth moon should be named Tombaugh of course, after the man who discovered Pluto.

  134. Bharath Ram -  July 28, 2011 - 2:35 am

    Why not break the convention of naming every planet or moon with a Greek god starting from this moon??

    Try something else…. May be gods and godesses fro, Hindu mythology as suggested in Rendezvous with Rama…….

  135. Daniel of Singapore -  July 28, 2011 - 1:48 am

    May be Cyreus , Plutamos , Ademans, Adamantors, Sendoris, Menteris, Pon Ardemis , Cytolpys, Mesania, Anderoid, Mentori, Acencianos,Bup ,Auputos.

  136. Onel -  July 28, 2011 - 1:31 am

    Maybe Achlys?

  137. JT -  July 28, 2011 - 1:18 am

    “Quartus” because in Latin quartus means “the fourth”.

  138. Willy -  July 27, 2011 - 11:25 pm

    Maybe name it Mickey!

  139. Steve -  July 27, 2011 - 10:21 pm


  140. Teivous -  July 27, 2011 - 10:18 pm

    Does the name really have to do with Mythology?
    Can it just be something really random like Warmoth, or Grandorathoroan?

  141. nargityshmorin -  July 27, 2011 - 9:48 pm

    Dudes and Dudettes of da world…..it should totally be named after the glowing ball from LoZ named Navi.

  142. Sabrina Robinson -  July 27, 2011 - 9:43 pm

    it* should be Hades :P

  143. Sabrina Robinson -  July 27, 2011 - 9:42 pm

    Hades!!!! i should be Hades

  144. Michael -  July 27, 2011 - 8:58 pm

    This isn’t a name but rather a thought…there are a lot of names to choose from, but everyone seems to be getting at the fact that it took a long time to find this one. Maybe naming it as some ultimate “hiding” or darkness names might not hold true if a fifth or more moons are found in the future?

  145. S.M. -  July 27, 2011 - 8:45 pm

    I think it should be Cerberus, Cronus, Persephone, Tartarus, Acheron, Cocytus, Phlegethon, Lethe, or Styx.

    Cerberus-Pluto’s three-headed dog
    Cronus-Pluto’s father
    Persephone-Pluto’s wife
    Tartarus-The darkest, deepest part of the underworld
    Acheron,Cocytus,Phlegethon, Lethe, Styx- The 5 rivers of the underworld

  146. Carmela -  July 27, 2011 - 8:40 pm

    Keeping up with the death/underworld theme, I think the new moon should be called Anubis, after the Egyptian jackal-God of the Underworld, or, Hel the Norse Goddess of Death and the Afterlife

  147. Mike -  July 27, 2011 - 8:40 pm

    The naming rights for the new Pluto moon should be auctioned (with a high reserve of say, 1 billion dollars) to an individual, company or country and the money donated to famine relief in Africa.

  148. Lily -  July 27, 2011 - 7:55 pm

    I propose the fourth moon of Pluto be named after ‘Erebos’, which translates to ‘darkness’. This is in line with the fourth moon being out of sight all these while. In addition, Erebos was the husband of Nyx (the moon named Nix), and the father of Kharon (the moon named Charon), their son. It would be nice to have the moons being closely linked to each other as one family.

  149. Eyewitness -  July 27, 2011 - 7:52 pm

    I have a name suggestion for “P4″ from Greek mythology, but first, let me dispel an assumption which seems rampant on this blog: the Pluto/death/Hades theme is not even present in the existing nomenclature. Hydra, one of the existing, named moons, is not part of the afterlife/underworld narrative at all.

    On the arguable assumption that any greek mythological source is consistency enough, I suggest Atalanta. In Greek mythology, Atalanta was distracted during a foot race (running) by each of three golden apples, supplied to her competitor Melanion (alternately, Hippomenes) by Aphrodite. Whenever Atalanta passed Melanion (Hippomenes) in the race, he would roll one of the apples ahead of her and she, distracted by their irresistable value and beauty (gold), would allow herself to pursue the apple and neglect her rival in the race, Melanion (Hippomenes). Thus, he won the race, unlike many before him, and won her hand in marriage as his prize.

    There is something charming to me about the imagery of this little moon “chasing after” the three bigger, more prominant, famously named moons, like Atalanta always trying to catch–or catch up to–each of the golden apples.

    My only concern is, admittedly, the name sounds somewhat too closely like the city of “Atlanta,” as though the named moon might unintentionally provide marketing promotion for the American city. The Greek masculinized form is Atalantos, perhaps a little less suggestive of the southern metropolis in Geogia. In either form, the translation is “equal value, equivalent merit” (from the Greek, a- “one, together” + talanton “weight, value” (cf. talent).

    I also seriously suggest the name “Venetia.” Not only is it lovely, but the charming vision of that little girl with her active mind gazing at the heavens brings to my mind the picture of the diminutive “P4″ “running with the big dogs,” Charon, Nyx, and Hydra, who have already made themselves known to earthly observation. I am sure the astronomers at the Lowell Observatory never expected a schoolgirl to “keep up with” their inquirying minds, however, famously, eleven year old Venetia Burney most certainly did.

  150. Michael -  July 27, 2011 - 7:46 pm

  151. slothdoctor -  July 27, 2011 - 6:50 pm

    Lethe is a great name
    Kampe is also a great name
    Cerberus is fitting

    What’s so special about Roman and Greek Gods?
    You could have easily named a planet/other thing Osiris or Thoth ir something.

    Who thought this up?
    Way to go Einstien

    You know, we would run out of names in Roman and Greek Mythology for planet names

    We should use something else!
    Maybe names of Dead People!

  152. email -  July 27, 2011 - 5:51 pm

    How about Pluto Jr.?

  153. Plaxius -  July 27, 2011 - 5:46 pm

    I think the fourth moon should be named Orpheus, after the man who traveled into the depths of Hades to bring his wife back from untimely death.

  154. Declan -  July 27, 2011 - 5:36 pm

    The moon should be named ‘Tycho’ after Tycho Brahe a 16th century astronomer known for his planetary observations.

  155. Shehreen -  July 27, 2011 - 5:34 pm

    i think they should name it PROMETHEUS because he was an import mythological figure he was known for his suffering and disobedience to the greek god, he was tied to a stone and the vulture would eat his liver and it would regrow and the vulture would eat it again. He suffered great pains in tryign to help the creation. I FEEL THIS NAME WOULd be suit able BECAUSE IT WOULD HOW SCIENTIST THAT DISCOVERY IS GOOD BUT TOO MUCH PRIDE AND PASSION FOR KNOWLEGDE LEADS TO BAD THINGS AND SUFFERING. it would show them that there creation after all mankind so they should be really wise

  156. Giselle -  July 27, 2011 - 4:39 pm

    I think that Pluto’s fourth moon should be named Ceberus. Theoretically speaking though, Pluto can not have a moon, because it is not a planet.

  157. Bellona -  July 27, 2011 - 4:35 pm

    Cerberus or Persephone!

  158. Celia -  July 27, 2011 - 4:25 pm

    I agree with Maria Mediarito wayyy above in the comments. Lethe is a good name for it. Also a good description too.

  159. Tina Tyra -  July 27, 2011 - 3:43 pm

    Asclepius, who was raised by Chiron. He was a great healer and hunter.

  160. zedmelon -  July 27, 2011 - 3:09 pm

    The Cerberus fixation likely results from–with few exceptions–that some folks simply don’t bother reading anyone else’s thoughts before blurting out what they’re evidently convinced is uniquely their idea. The word (with a couple misspellings) is literally listed 74 times before my other comment (July 26, 2011, 10:20), and several times since.
    (egrep -i “cerberus|cereberus” webpage | wc)

    By now it’s not necessarily a huge secret, but please be considerate of those who maybe haven’t yet seen it. Or read it.

  161. Marciano -  July 27, 2011 - 2:23 pm

    they should name the new moon Mickey Mouse… since pluto is his bests friends name..!!!

  162. Ario -  July 27, 2011 - 2:21 pm

    Why all mythical Gods and Goddesses of ancient Greeks, Romans or whatever else comes to mind from that part of the world?
    What is wrong with using some trule legends of mankind? Let’s say Cyrus in appreciation to his first human right charter.

  163. Kit Cloninger -  July 27, 2011 - 2:11 pm

    Cerberus seems to have the most votes so far….I know next to nothing, but am always interested in learning about this stuff…perhaps we should keep it simple from now on and name it Francis, or James…..although we could just look at it without naming it and be equally satisfied..after all it is a restless evil, and endless i should add. Enjoi

  169. tonyaka -  July 27, 2011 - 12:47 pm

    I think it is time we begin honoring modern heros who’s brought inspiration to the newer generations. It is because of our modern space program that these kinds of discoveries are being made. When asked “What is Pluto?” the top two answers will most likely be – the demoted planet or the cartoon dog. So, what better name for a mini moon than “Pup”. I vote to name the new moon Pup. It’s probably what Disney would name Pluto’s puppy. Regards.

  170. Annime -  July 27, 2011 - 12:22 pm

    Daimon-the greek derivative of “demon” or a entity of knowledge. Like this moon, it remains far from the pantheon of gods and goddesses but remains a Deified hero or soul that is blessed enough to remain close at their periphery. This moon is unknown to have any major impact on our space research (demons were either helpful or harmful) and like a demon, it’s timeless existence is unknown until found but is nonetheless the intermediary spirit between men and gods, or in in our case space and humans.

  171. Dilia Bobadilla -  July 27, 2011 - 11:55 am

    In keeping with tradition any “mithological name” would do. But who has all the time to read about mithology. P4 (Pluto’s fourth moon) is readily interpreted as Pluto’s fourth moon. It makes more sense to me (even scientifically) than all of the inventions of the goddesses. It comes to be as a natural hairstyle. Right???

  172. Annime -  July 27, 2011 - 11:45 am

    Let’s rename P4 Obama, after the god of economic destruction, who has taxed us and generations beyond us with his War on Prosperity, turning a once thriving nation into a third-world has-been while condemning all of its citizens to a death-by-a-thousand-cuts version of financial ruin.

  174. Antonio -  July 27, 2011 - 11:19 am

    Orcus. I’m not quite certain the mythology around the name, but Pluto was often mistaken for him.

    And I like Pratibha’s comment. It would be an amazing conclusion for the era.

  175. Dae -  July 27, 2011 - 11:08 am

    why is everyone suggesting Cerberus, Persephone, and ect. Why not other gods like the indian gods and egyptian gods why not them it does not have to be greek mythology? i think it would be named after Styx

    Cerberus, definately. It all fits that way.

  188. jesse -  July 27, 2011 - 8:18 am

    How about Proserpina, or Proserpine, or Prosperine? Pluto is the Roman god of the underworld, hence the Roman name Proserpina instead of Persephone, the Greek name. Besides, there’s already and asteroid named, 399 Persephone.

  189. rdococ -  July 27, 2011 - 8:14 am

    I have three names:
    - Hercula: originate from Hercules
    - Quattuor: It means 4 in Latin.
    - Luna Quattuor: It means Moon 4 in Latin.

  190. Jessica -  July 27, 2011 - 8:13 am

    Proserpina is Pluto’s wife in Roman mythology by the way.

  191. Jessica -  July 27, 2011 - 8:12 am

    It should be named Hecate, the Greek goddess of magic, or maybe Proserpina.

  192. Zoe H. -  July 27, 2011 - 8:04 am

    Persephone, definitely.

  193. aishu -  July 27, 2011 - 7:44 am

    i would like to vote for the name ‘LETHE’ and ‘Cerberus’.
    many names suggested here is already used as names for moons of other planets.

  194. Dominic Toscano -  July 27, 2011 - 7:35 am

    I’m thinking either:
    Basically any figure or object from Greek/Roman mythology commonly associated with Hades/Pluto.

  195. Lawrence -  July 27, 2011 - 7:27 am

    In keeping with the Roman theme, the clear choice is: Proserpina. This is the equivalent of Persephone in Greek mythology. Were we to name it Persephone, the sub-planet would need to be called Hades.

  196. Michael -  July 27, 2011 - 7:01 am

    per the story thats already being told by the names of the moons already, what is needed is the river Styx to be more complete. Cerebus would be a great name but from a storyboard perspective … Styx should be next.

  197. leslie -  July 27, 2011 - 6:39 am

    Aletheia- relating to Lethe, but meaning unconcealment or Truth-see Heidegger

  198. RABIA -  July 27, 2011 - 6:37 am

    i will name it “Plutoid” one can guess why.

  199. Zuki -  July 27, 2011 - 6:19 am

    It’s clear this meaningless moon of a defrocked planet is getting the full Greek & Roman treatment. It’s all very tedious and in need of “something completely different.” I would suggest the new rock be called “Billy”

  200. kazoolarlina -  July 27, 2011 - 6:02 am

    it should be named Styx, after the river Styx opon which gods swear oths
    and it is the river which Charon ferries souls across. it just works

  201. Rachelle Aviv Goldberg -  July 27, 2011 - 5:25 am

    I think of all these names, Maria Mediarito’s suggestion, Lethe, and also Cerberus are the most popular here. I am personally voting for Lethe as the reasoniing of lovely, and possibly Albus, as Prathiba said.

  202. Deni -  July 27, 2011 - 5:23 am

    Terti, meaning third in latin?

  203. bugattiforlife283 -  July 27, 2011 - 4:49 am

  204. bugattiforlife283 -  July 27, 2011 - 4:47 am

    optimus prime lol

  205. bugattiforlife283 -  July 27, 2011 - 4:45 am

    i was thinking Tartarus. its a perfect name for a small floating probably barren wasteland in deep space. just think: Pluto, and its moons Charon, Nix, Hydra, and TARTARUS. it’s an awesome name. and, if you guys are only looking for greek/roman gods and/or goddesses and monsters or whatever, Cerberus is a good name. but please please PLEASE name it Tartarus.

  206. BanrionTine -  July 27, 2011 - 3:57 am

    Persephone has already been suggested, but what about Kore or Proserpina, which are alternate names for Persephone? Personally, I would like to see it named Kore.

  207. Rachel -  July 27, 2011 - 3:55 am

    How about “Tartarus”, Nyx’s brother, God of Deep Place, also the name of the abyss in the Underworld reserved for torment and suffering.

  208. TheKingBrown -  July 27, 2011 - 2:58 am

  214. Pratibha -  July 26, 2011 - 11:00 pm

    Why not Albus? Moon is considered white (Albus means white/pure) and it would be a fitting tribute to Albus Dumbledore, the great wizard, considering that we have just bid goodbye to the last Potter film Harry Potter and the Deathly Hallows Part 2. It would also encapsulate our times — the Potter era.

  215. John -  July 26, 2011 - 9:59 pm

    Since the moon is so small – a mere 13-34km across – I’d suggest Obol: the coin which was placed in the mouth of the dead in order to pay the ferryman, Charon, for passage across the river Styx.

  216. Andrew -  July 26, 2011 - 9:54 pm

    It should be named Furiae or Furia
    It is a long story but basically Furiae is Latin for Furies, (Furia is the single tense) and The Furies are the helpers of Pluto or the punishers and tormenters of souls… What? They said it might be scary.

  217. Eyewitness -  July 26, 2011 - 9:48 pm

    What is this thing for Cerberus? When did the three-headed dog who guarded the gates of Hades become a populist cause celebre?

  218. Justin -  July 26, 2011 - 9:39 pm

    I shall provide the name of Tartarus! this moon has been in darkness for a while and Tartarus is the mythological deepest and darkest pit in the underworld.

  219. Johnny -  July 26, 2011 - 9:34 pm

    Or…. Kratos

  220. steph -  July 26, 2011 - 9:12 pm

    Why not Hemera. She is the greek goddess of the daylight and the sun. Then there would be both darkness and daylight.Nyx and Hemera.

  221. Kate -  July 26, 2011 - 9:03 pm

    And here are the meanings, in case you were wondering . . .

    One of the three Furies. Her name means unceasing, and she is constantly angry.
    Another of the three Furies. Sister to Alecto and Tisiphone, along with the three Fates. Her name means to grudge, and she is always jealous of everyone.
    Tisiphone is – along with Alecto and Magaera – one of the three Furies. Her name means avenging murder, and she will punish anyone for anything.

    I chose the three Furies because they relate to Hades (Greek form of Pluto).

    His name means afterthought. I chose his name because even though Pluto has been known of for a while (81 years), they have just discovered this moon.
    This name is the original Greek form of Pluto, and I thought it would fit that Pluto’s moon would have a similar name as its planet.
    This name means dawn. I chose it for Pluto’s moon because it has been in the “dark” (or night) for 81 years (since Plutos discovery), and it is only now that it “comes to light” (or dawn). Get it?
    Father of Hades/Pluto. Need I say more?
    Her name means hidden/forgotten. Pluto’s fourth moon has been hidden, and now it’s discovered. Is any more explaination necessary?
    This name means the darkness of the night. Hidden in shadows up until now, P4 is truly in the darkness of the night because it is so far away from the sun.
    Meaning boundary/limit, this name is fitting because Pluto is one of the farthest planets from Earth to be discovered – making it a boundary.
    This name means moon. Do I have to say more?
    Means death in Greek. And since Hades/Pluto is the god of the dead, it seems fitting.

  222. Frank A. Lucas -  July 26, 2011 - 9:02 pm

    “XERXES” xerxes would be the exact name for the fourth moon of pluto.

  223. Frank -  July 26, 2011 - 8:55 pm

    “XERXES” The right name for the fourth moon orbiting pluto.

  224. Kate -  July 26, 2011 - 8:38 pm

    I’ve got a few Greek mythology names for you . . .

  225. Madi -  July 26, 2011 - 7:41 pm

    You should call it Pigfarts (from A very Potter Musical)

  226. Kitty -  July 26, 2011 - 7:12 pm

    Cerberus is the best choice.

  227. Victor -  July 26, 2011 - 6:54 pm

    Either greek/roman spelling.
    what have you:



  228. bex -  July 26, 2011 - 6:19 pm

    Having thought about all the Roman names, classic Greek names, great works of literature, astronomical terms and mythology, I suggest DAVE.

  229. Heiwajima -  July 26, 2011 - 5:55 pm

    Cerberus! If not then it can be Nyx, Morpheus, Hypnos, or Tarturus. We need to stick to the whole underworld, creepy-dead theme.

  230. Jen -  July 26, 2011 - 5:52 pm

    Well if you stick with mythology, then there could be lots. I like the suggestion ‘Persephone’ and Lethe, Erinyes, Erebus, Cerberus, Tantalus, Acheron, Cocytus, and Phlegethon all work.
    And for those who think it should be a happier one, you could name it Elysium because that’s a good thing in Hades.

  231. Chuck -  July 26, 2011 - 5:16 pm

    Why don’t they name it after another 4th….Shemp.

  232. ME again!i!i!i! -  July 26, 2011 - 5:14 pm

    wow… naming a moon of a lesser planet… how pathetic.
    i mean honestly, have you no pity? or shame?
    it’s not even ours… that’s like naming an ancient ruin “pudding” it may not seem insulting but judging by how much things have changed the languages and mythology is all mixed up.
    would you truly like any of these names for yourself? i mean how ridiculous does being called “Cerberus” sound? i wouldn’t like any of these names for me.
    we name things because they show ownership of an object.
    we don’t own this.
    its not ours.
    how would you like to be owned?
    don’t name things that aren’t yours to keep.
    not one name in the universe can describe something in full detail and divinity.
    don’t name it. let us call it what we want.
    thank you,
    Please stop naming things that aren’t yours, Sincerely,

  233. Chuck -  July 26, 2011 - 5:12 pm

    I like P4 or after.

  234. Mike McKelvy -  July 26, 2011 - 5:04 pm

    The Greek Cerberus is quite fitting, better known than Roman Kerberus.

  235. Josh -  July 26, 2011 - 5:03 pm

    It should be Cerburus

  236. Josh -  July 26, 2011 - 5:02 pm


  237. Anthony -  July 26, 2011 - 4:33 pm

    Perhaps Cocytus/Kokytos, an underworld river, or Moros, the personification of doom, the brother of the Fates/Moirae, and the son of Nyx. The already mentioned Persephone or Thánatos would also make good names.

  238. Ejaaz -  July 26, 2011 - 4:17 pm

    I would say erinyes the romans called them: Dirae (they tortured those who had done evil deeds (i.e. kill someone, break an oath) they’re also kind of like Hades/Pluto’s helpers, so i think naming the new moon this would be appropriate)

  239. Sean Jeffries -  July 26, 2011 - 4:05 pm

    I believe that the moon should be called Acheron the river of pain it fits the underworld theme and then if all else fails it should be named Elysium after the Elysium fields where the dead go if the were heroes or good people. Hoped I helped!

  240. Rita -  July 26, 2011 - 4:03 pm

    Who cares what they call it!! Why even waste your time with suggestions!! As if they will ever use any of them to begin with!!

  241. Lefty -  July 26, 2011 - 3:58 pm

    How about OPRAH or HARPO or better yet Luna

  242. Rita -  July 26, 2011 - 3:55 pm

    Who cares what they call it!! As if they are really going to take into consideration your suggestions!!

  246. Jack B. -  July 26, 2011 - 3:06 pm


  247. Sarah -  July 26, 2011 - 2:57 pm

    It should be named Mickey!Remember Pluto the dog?

  248. Emily -  July 26, 2011 - 2:54 pm

    Pomegranate, fruit of the underworld!

  249. alex -  July 26, 2011 - 2:27 pm

    Make the name modern. Pluto is a planet that is not a planet, a dwarf planet. This is a very small moon of a planet that is not a planet. So it is like a moon. Should it be only considered an astroid? It is very small like an apple. So let name it “midget apple.”

  250. Percy ;) -  July 26, 2011 - 2:19 pm

    i think it should be Nico. ;)

  251. Marlon -  July 26, 2011 - 1:57 pm

    Can we change Nyx and Hydra’s names while we’re at it?

  252. Marlon -  July 26, 2011 - 1:54 pm

    Dear, Em Spearing, Pluto was Mickey’s dog. Your childhood has been revoked

  253. Bill Watson -  July 26, 2011 - 1:51 pm

    Dang, Persephone is a really good one too. Mostly I love that name. And then because the kidnap of Persephone really fits the whole being a satellite of Pluto thing.

  254. Alan Turner -  July 26, 2011 - 1:47 pm

    If Pluto is a planet then the things all around should be some names to accompany it.
    Ask Walt Disney. Mickey, Minnie, Donald, Hughie, Louie, Dewie. ????????????????????????

  255. Marie Verna -  July 26, 2011 - 12:22 pm

    Why all the darkness and death?

    This new moon is a great thing, something to celebrate. What means “Yeah” in Greek?

  256. Spencer -  July 26, 2011 - 11:57 am


  257. Dave -  July 26, 2011 - 11:49 am

    They should name it Starbucks so NASA can get more funding.

  258. AMan -  July 26, 2011 - 11:43 am

    It’s name…is Robert Paulson

  259. Robert -  July 26, 2011 - 11:42 am

    I think Hermes is as good a name as any: not only was Hermes a psychopomp but he was the god of boundaries as fitting Pluto’s position at the boundary of our solar system.

  260. Robert -  July 26, 2011 - 11:37 am

    Lori you are wrong! My name for P4 is Giyar-Gerabalama. But nick name it Giyar.

  261. Williams -  July 26, 2011 - 11:36 am

    please name it RAIZA.

  262. Em Spearing -  July 26, 2011 - 11:33 am

    Don’t overlook the obvious. Pluto was Goofy’s dog for corn’s sake. That moon is Goofy!

  263. Robert -  July 26, 2011 - 11:30 am

    It defanatly should be Giyar-Gerabalama.DEFATLY you should name P4 that.Defanatly. Its my exact name for P4. GIYAR-GERABALAMA!!!!!!!!!

  264. abee -  July 26, 2011 - 11:27 am

    it should be la cuarta luna spanish for fourth moon

  265. Robert -  July 26, 2011 - 11:05 am

    Pluto’s 4th moon should be named Giyar-Gerabalama.

  266. louis paiz -  July 26, 2011 - 10:51 am

    with my respects to all of you;participants but don’t you think that its time to abrase life and god will;everything i have had herd is dead underworld or cerberus the dog gardian of hell.why not beauty change,friendshipetc. i sujest, hermes because is amoon. thank you very much.

  267. Jibra'il -  July 26, 2011 - 10:51 am

    How about Urizen (a pun for “your reason” and is greek for “to limit”). Urizen is one of the four Zoas who make up the four-fold individual (P4 = four-fold individual). Furthermore, Urizen is an Eternal who is separated from the rest who then creates the fallen material universe, Ulro. Since Pluto is no longer considered as a planet, Urizen is actually befitting for the situation.

  268. L Bosma -  July 26, 2011 - 10:45 am

    Exodus 23:13
    “Pay attention to all that I have said to you, and make no mention of the names of other gods, nor let it be heard on your lips.
    How far we have fallen to ignore the words of Yehovah! No wonder all of creation is crying out for the sons of God to be revealed. Another flood or drought or hurricane anyone? Just keep ignoring Yehovah, or turn to him and be saved from the fiery wrath about to be poured out!

  269. Neta -  July 26, 2011 - 10:41 am

    I think, in honor of the last Harry Potter, it should be named Fluffy, after the three headed dog. Which is actually J.K. Rowling’s version of Cerberus.

  270. A Ward -  July 26, 2011 - 10:27 am

    I think “Erinyes” would be an appropriate name. Persephone would be good as well, but she was too significant to be a moon of Pluto as she is a goddess. Erinyes, however, are associated strongly with Pluto / Hades and are born from Nyx, which is already a moon of Pluto.

  271. Umm -  July 26, 2011 - 10:21 am

    what about Keres daughter of Nyx or Moros who ends a persons life after their thread if life is cut or u could use the cutter Parcae (fate) even the gods feared them or Morta the one who chooses how the mortal or immortal will die.

  272. zedmelon -  July 26, 2011 - 10:20 am

    Hey! How about Cerberus? I’ll bet no one in any of the previous 6,000 comments has thought to suggest that.

    …not seventy times anyway…

  273. CJ -  July 26, 2011 - 10:12 am

    Since Persephone, Cerberus and Orpheus are all asteroids I belive, Minthe (an ill fated love of Pluto/Hades), would get my vote.

  274. Morraha -  July 26, 2011 - 10:08 am

    My vote is for either Lethe or Cerberus.
    I like the beauty of Lethe but Cerberus seems a far more fitting title as the guardian of the gates.

  275. Umm -  July 26, 2011 - 10:01 am

    what about Tartarus It is Hades dungeon for torture and suffering
    or Minos judge of the dead

  276. D.A. -  July 26, 2011 - 9:51 am

    Now is the opportunity to name it either “Mickey” or “Donald”.

  277. Rajagopal -  July 26, 2011 - 9:40 am

    I would like to propose Hindu vedic name… Prahlad

  278. Margaret Lea -  July 26, 2011 - 9:37 am

    Tho i have not read all the entries, i would like to echo Maria M’s vote for “Lethe” as the name for Pluto’s 4th moon. It is a positive and cleansing presence in the midst of all that darkness in the Underworld. (Land of the Dead)

    Lethe is a river there, a drink from which is believed by the ancient Greek’s gods, causes oblivion and forgetfulness as the sins of the past are washed away in her waters.

    Perhaps a reliever of Suffering, making Hell, not such a bad place to be.
    i once heard “If You are in Hell, keep going!!!!!”

  279. Kyle -  July 26, 2011 - 9:35 am

    I think Achilles or Thetis or Styx. Achilles was the first to bathe in the Styx. Thetis was the mother of Achilles. So I think either of them.

  280. Didi -  July 26, 2011 - 9:16 am

    Jimmy Currin suggested DIS but I think DAT is better.

    Uh! How about Goofy, Minnie or even Mickey ?

  281. ZMan -  July 26, 2011 - 8:37 am

    I know I’m not the first to suggest Cerberus, but it really is a good name. This 4th moon is the outermost moon, so it’s like a guard, just like Cerberus is the guard of the Underworld. It goes with the Greek theme and it really fits!

  282. Aman Dalal -  July 26, 2011 - 8:32 am

    I think that Cerberus is the appropriate name for the planet. The three headed dog protects the gates of the Underworld.

  283. Jerm -  July 26, 2011 - 7:56 am

    I think it should be called Kevin Bacon. So in the future when people look at a star chart and are passing by Pluto on their way to where ever, they can see that Pluto has four moons. Three of them named in traditional form, then when they look at the fourth moon they could be like, “Kevin Bacon?!? Who the heck is Kevin Bacon?” It would be like a cosmic joke done by us on the future.

  284. slothdoctor -  July 26, 2011 - 7:49 am

    Lethe would be nice
    So would Kampe, a prison guard of the underworld
    Cerberus too, the prison guard of hell itself.

    The scientists should have named the moons after the five rivers of hell:

    Maria Mediarito, you are somewhat right about Lethe

  285. Lori -  July 26, 2011 - 7:38 am

    Lethe seems the most appropriate.

  286. Daniel -  July 26, 2011 - 7:35 am

  289. Lee -  July 26, 2011 - 6:21 am

    They should just sell the naming rights for a couple of years to big companies – I”d be happy for the moon to be called “Coke” if the money gained from that were put back into astronomy

  290. Don Beecham -  July 26, 2011 - 6:16 am

    The name should be ‘Zoe’ which from the greek is Spirit. The spirit surrounds pluto and keeps watch.

  291. ored -  July 26, 2011 - 5:54 am


  292. Raj -  July 26, 2011 - 5:32 am

    Deimos (one of the moons of mars)

    I take no credit for what others have posted.

  293. Chloe -  July 26, 2011 - 4:37 am

    1) Styx
    2) Cerbereus
    3) Osiris
    4)Tautarus-the pit of the underworld where the most evil dwell.
    5)Κρυφό- Greek for ‘Hidden’

  294. anonymous -  July 26, 2011 - 4:28 am

    Chimaera, Cerberus, Tyhoeus

  295. maityog -  July 26, 2011 - 4:12 am

    I think Pluto’s newly discovered moon should be named Kronos, the titan that rules over time. Or Ouranos the father of all titans and lord of the sky.

  296. clark -  July 26, 2011 - 3:56 am

    Kratos na lang para masaya. . . .

  297. Silvio -  July 26, 2011 - 3:43 am

    I’d call ir Cerberus, or Proserpina.

    Proserpina is the roman name of Persephone, wife of Pluto. If the planetoid is called by the roman name Pluto, and not the greek Hades, I think it would be more adequate.

  298. kannnan -  July 26, 2011 - 3:27 am

  299. Madelle -  July 26, 2011 - 3:12 am

    Since Pluto has recently been stripped of the right to be called a planet, pluto is almost like the bastard son of our solar system… Therefore, I think the new planet should be named Spurius, which is latin for bastard. The Merriam Webster Dictionary defines it as something that is “outwardly similar or corresponding to something without having its genuine qualities”

  305. Victor -  July 26, 2011 - 2:16 am

    IMO, the fourth moon will be called Persephone, after the wife of Hades.

  306. gerrard -  July 26, 2011 - 1:50 am

    I think it is best to name it Cignus

  307. matt -  July 26, 2011 - 1:47 am

    Stygian… I find it has a nicer sound than ‘Styx’.

    Charon, Nix, Hydra, and Stygian.

    Lethe is interesting, too.

  310. Kenny Smith -  July 26, 2011 - 1:29 am

    I agree with Maria Mediarito. Although it doesn’t fit the theme, She brings up a valid point.

    Cerberus because he guards the gates of the underworld and if people mention the three headed dog they may recognize it. Cerberus is pretty popular and important to the myths of the underworld.
    Or Persephone or as the Romans would say Proserpine. She does revolve almost half her life in hades. Why not? It makes sense.

  316. Andrew -  July 26, 2011 - 1:19 am

    I think HARRY POTTER should be it gwendylyn!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  317. Andrew -  July 26, 2011 - 1:17 am

    Or Pemious

  318. Andrew -  July 26, 2011 - 1:16 am

    I think it should be Takuya

  319. JonnyUtah -  July 26, 2011 - 12:18 am

    Well, it’s a small moon orbiting Pluto…

    How about ‘Mini P’?

    It rhymes with Mini Me and reminds us of small people.

    Fun for everyone.

  320. Joshua -  July 25, 2011 - 11:54 pm

    Maybe Proserpina, th latin godess who is Pluto’s wife. Or maybe Morpheus or Phantasos or Phobetor(dream gods) or Thanatos or Hypnos or Melinoe(ghost goddess)or Cerberus or Eurynomus (demon) or Lethe or Cocytus or Acheron or Pyriphlegethontus or Styx (rivers of Hades) and that’s it.

  321. aaron -  July 25, 2011 - 11:52 pm

  324. mohammad -  July 25, 2011 - 10:43 pm

    it has been in hiding or waiting so it should be called al-mahdi or mahdi…..thanks

  325. Charles -  July 25, 2011 - 10:22 pm

    Most possibly Styx after the river, or perhaps Tartarus (where bad people are punished), or Elysion.

  326. KK -  July 25, 2011 - 10:14 pm

    I think it should be called Anubis, after the Egyptian god of embalming.

  327. gwendylyn -  July 25, 2011 - 9:18 pm

    either athena persephone cerberus or VOLDERMORT!!

  328. Octavio -  July 25, 2011 - 9:11 pm

    “Chronos” for the timing of the discovery. Since it was discover after Pluto was unclassified as a planet. Call it ”too late” of a discovery.

  329. KansasRoots -  July 25, 2011 - 9:00 pm

  333. Sophi -  July 25, 2011 - 8:14 pm

    It should be Orcus- he was a god of the underworld. Orcus was basically the Roman god of punishing those who do not honor their oaths.

  334. Rachel -  July 25, 2011 - 8:11 pm

    Lethe, the river of forgetfulness could be a possible choice or Cerberus, the three-headed guardian dog of the Underworld could also be good.

  335. raul -  July 25, 2011 - 8:07 pm


  336. Georgia -  July 25, 2011 - 7:56 pm

    I think the name Lethe is fitting from what I’ve read in some coments.

  337. Illz -  July 25, 2011 - 7:54 pm


  338. britt w -  July 25, 2011 - 7:38 pm

    Typhon or Ladon

  339. Diamond -  July 25, 2011 - 7:38 pm

    I think Calypso. She was a lesser greek goddess and her name means the concealer. Pluto is now a “lesser planet” (dwarf planet) and this moon has been hidden-or concealed because it was just found.

  340. Marshall Burlew -  July 25, 2011 - 7:18 pm

    I think it should be named after the Greek God of Death; Thanatos, because the moon is most likely; far away and it’ll be very dark just like Thanatos. Plus, Thanatos was a son of the 2nd moon of Pluto, Nyx in Greek Mythology. So, I think it should be named after, Thanatos.

    How about Fenris? He was the dog in Greek mythology that was tethered down and kept on breaking his tethers. Fenris said that he would only cooperate if someone would stick their hand in his mouth. Tiw (the god after which Tuesday is named) was the only brave enough to do it and he got his hand bitten off.

  342. Lorenzo -  July 25, 2011 - 7:14 pm

    I think Lethe is the best. Proserpina is second. I like it better than Persephone in order to keep the Mythology straight with Pluto. Cerberus has already been used. I thought I heard of something with the name Hypnos, but I could be wrong. I do like the name Mickey, but we need to have Lethe first, being the river, then if they discover a fifth moon, then we can slip a mickey into it :D

  346. Zach -  July 25, 2011 - 6:49 pm

    Call the new moon Persephone. Cause Since in Greek/Roman mythology, she was the goddess of the underworld and was the wife of Hades/Pluto, so it would be appropiate to call it that.

  347. Colt -  July 25, 2011 - 6:48 pm

    Pluto – a name given to Hades, under which he is identified by the Romans with Orcus.

    Orcus – the ancient Roman god of the underworld, identified with the Greek Pluto, or Hades.

    Orpheus – Greek Legend. a poet and musician, a son of Calliope, who followed his dead wife, Eurydice, to the underworld. By charming Hades(aka Pluto), he obtained permission to lead her away, provided he did not look back at her until they returned to Earth. But at the last moment he looked, and she was lost to him forever.

    I say, name the moon, ORPHEUS

  348. Brandon -  July 25, 2011 - 6:25 pm

    …Kratos.. lol

  349. HPFan -  July 25, 2011 - 6:25 pm

    I think Anubis (the Egyptian) God of the dead would be a good name for the 4th moon

  350. Sakura -  July 25, 2011 - 6:22 pm

    Proserpina, Roman equivalent of Persephone

  351. Larissa -  July 25, 2011 - 6:20 pm

    Some people have already mentioned this name and I agree with them. It is a perfect name for this new moon.

  352. John -  July 25, 2011 - 6:19 pm

    The name should be “Mare”

  353. Vanessa -  July 25, 2011 - 6:18 pm

    Oops. I just read Kalontas’s comment about the asteroid named Cerberus. (Thanks, Kalontas.) Ah, well. Something else, then. Hecate would be good. Or Persephone. or virtually any of the other things people have suggested here.

  354. Vanessa -  July 25, 2011 - 6:15 pm

    I agree with the suggestion of ‘Cerberus.’ It has the Greek Mythology/Underworld connection, and Cerberus is a relatively minor being (not a god or anything like that) so I think it would be fitting for a small moon. And no, I am not saying this only because others suggested it. I think it would be a good name, that’s all. Plus Cerberus is one of my favorite figures from Greek Mythology.

  355. Gasper -  July 25, 2011 - 6:12 pm

    I think that Alecto would be a good name, because the poet Virgil says that she is the daughter of Pluto.

  356. Josh -  July 25, 2011 - 5:57 pm

    Call it… Josho

  357. TNW -  July 25, 2011 - 5:55 pm

  360. E.V. -  July 25, 2011 - 5:39 pm

    Definitely Erebus or Thanatos (Mors in Roman mythology). Either one would so totally fit into the theme.

  361. ME!i!i!i! OBLIVOUS -  July 25, 2011 - 5:35 pm

    I don’t think it should have a name… i mean honestly, wouldn’t it be sorta cool if it could be the first recorded moon without a name?
    besides, we name things because their ours, ask yourself s, do we own this?
    and if it didn’t have a name than we could call it whatever we wanted.
    if it is named most will be disappointed that the name was not of their choosing… so with great regret, they would name it anyone THEY please anyways. If they did listen to this we would all be outvoted no matter what.
    So why name it?
    keep it unnamed, it could be the most obvious thing ever!i!i!i!
    not everything in mythology has a rightful name, not one that suites it to the full extent, so why give a name that will not be suitable.
    i hope you stop naming things that aren’t yours and leave things as they are.

    how about chimera

  365. Bear -  July 25, 2011 - 5:23 pm

    There can be but one name for this “way out there” moon that has remained hidden all these years: Zaphod Beeblebrox or just Zaphod for short.
    Zaphod Beeblebrox, of Hitchikers Guide to The Galaxy fame, was as I’m sure you all remember, the inventor of the Pan Galactic Gargle Blaster. Try and top that all you Greek Gods! But more to the point, like Pluto’s P4, Zaphod managed to hide his second head, most of the time. Actually we are naming P4 after that second head, which happens to have the same name as the first, but I digress. So there you go. What better appropriate characterization can there be?

  366. Timi Akinsola -  July 25, 2011 - 5:23 pm

    Scythos, signifying death. (Real Word: Scythe)

  367. Ben -  July 25, 2011 - 5:20 pm


  368. Glass -  July 25, 2011 - 5:19 pm

    Persephony. I’m surprised one of the moons hasn’t been named for her already. Look at how many lovers Jupiter had, and they’re all represented. I’m pretty sure most of us would agree, it would be fitting to have Pluto’s wife by his side.

  369. Anne -  July 25, 2011 - 5:07 pm

    Phoebe would be a great name. And, in my heart Pluto will always be a planet!

  370. pamela odidi -  July 25, 2011 - 5:01 pm

  374. Bob -  July 25, 2011 - 4:43 pm

    How bout Odysseus or Ulyssees becuase he is the hero of the most important work of literature in history, and because he was inside Hades (or pluto) at one time.

  375. Sin -  July 25, 2011 - 4:32 pm

    I love how so many people keep saying “it’s obvious”. How very arrogant.

    Anyway, some suggestions:

    Protogenoi (Primordial Gods who Are Responsible for the Universe):

    Erebus: Embodiment of absolute darkness, and a realm in the Underworld. A place AND a god. Husband of Nyx, who is the goddess of night.

    Tartarus: The great Hellpit, a place AND a god. He was the father of Typhon, by Gaia.

    Lesser Known Gods:

    Thanatos: God of death, a being who hates all, even the gods – whom he cannot kill.

    Moros: God of doom, who deems when each and every thing shall die.

    If anyone suggests “Kronos from Percy Jackson”, I’m going to keel over. That’s called Rick Riordan screwing up the myths. (IE, he combined Cronus, harvest Titan, with Chronos, the Protogenos of time. Completely unrelated.)

  376. Collan Neal -  July 25, 2011 - 4:25 pm

    Tartarus is my most fitting Greek Mythological choice. Because it’s below Hades, i.e. very very far away, & Fittingly past Charon, at least in Greek mythology

  377. dylan -  July 25, 2011 - 4:21 pm

    or even “discovery” celebrating the last shuttle mission. it would also be in honer for those how died during the shuttle program and those who put their harts into the program!

  378. Cholisose -  July 25, 2011 - 4:20 pm

    Keroberus, the magical guardian of the Clow Cards.

    Tartarus – It is a deep, gloomy place, a pit, or an abyss used as a dungeon of torment and suffering that resides beneath the underworld in Greek mythology
    Nekyia – rite by which ghosts were called up and questioned about the future

  380. Shea -  July 25, 2011 - 4:16 pm

    I like Thanatos. It ties in with Hades, death and the underworld and has a great sound to it.

  381. dylan -  July 25, 2011 - 4:14 pm

    i would name it “discover”

  382. Justin -  July 25, 2011 - 4:07 pm


  383. Savannah -  July 25, 2011 - 4:05 pm

    How about Tartarus? That is where the bad dead go in mythology.

  384. Laurel Kornfeld -  July 25, 2011 - 4:02 pm

    As for names, Proserpina or Persephone are great, as is Kore, another name for Persephone. Hecate is also a good choice, as she is the goddess of the crossroads between life and death. Kali is the Hindu underworld goddess.

  385. edcetera -  July 25, 2011 - 3:51 pm

    Name it


  386. Shelby -  July 25, 2011 - 3:47 pm

    i think its name should be morpheus, after the god of dreams

  387. PoPrincess -  July 25, 2011 - 3:42 pm

    I think it shud either be named Cerberus, Lethe, or Persephone. :D
    Those r the best ones so far. :)

  388. Kalontas -  July 25, 2011 - 3:42 pm

    Did anyone above me check if there isn’t already a thing named like his proposal? There is a Cerberus (asteroid 1865 Cerberus), however I can’t find Erebus (I could swear I heard of a planetoid by that name).

  389. Laurel Kornfeld -  July 25, 2011 - 3:36 pm

    Please do not accept Pluto’s controversial demotion as fact when it is not–it represents only one view in an ongoing debate. Only four percent of the IAU voted on this, and most are not planetary scientists. Their decision was immediately opposed in a formal petition of hundreds of professional astronomers led by New Horizons Principal Investigator Dr. Alan Stern. Dwarf planets are planets too!

  393. OnceNefarious -  July 25, 2011 - 3:02 pm

    I agree with Maria Mediarito, who said,

    “I’d like to propose the name ‘Lethe’. Which is one of the rivers in the Underworld, which the dead bathe in so that may ‘be cleansed of their mortal memories” and be reborn or resurrected. If my memory does not fail me, ‘Lethe’ means concealment. To ‘conceal’ something is to hide it, and this 4th moon has only been discovered far later than the other 3 moons. So I suppose in some way, you could say ‘P4′ was in ‘hiding’.”

    Lol, I know a prodigy when I hear one.

  394. slothdoctor -  July 25, 2011 - 3:01 pm

    How about a demon’s name?
    Lucifer, Leviathan, Baal, etc?

  395. slothdoctor -  July 25, 2011 - 3:00 pm

    Cerberus duh!
    Then again, there are lots of monsters/things in greek mythology
    For anything other than Cerberus:

    Then again, maybe something else related to hell or something
    Why the heck must it be related to hell anyway?
    Or even greek mythology?

  396. Fungible -  July 25, 2011 - 2:58 pm

    If we want to keep with the Greek/Roman Underworld theme, I vote Cerberus or Lethe or Persephone.

    On the other hand, maybe it’s time Pluto got a name that’s not so dark and depressing. Mickey would be pretty funny.

  397. carogo -  July 25, 2011 - 2:51 pm

    My vote also goes to Cerberus, the three-headed dog-guardian of the underworld, but also:
    Morpheus, god of dreams, and son of Nyx (one of the current moons of Pluto);
    Orpheus, the lyre player, the only mortal to enter the underworld and leave alive;
    Eurydice, Orpheus’ wife, whom he came to bring out of the underworld and almost succeeded;
    Sisyphus, a king sentenced to eternally roll a stone up a hill only to see it descend before he can push it to the top; another underworld character;
    Thanatos = a Greek daemon of death.

  399. Danny -  July 25, 2011 - 2:47 pm

    I, myself, have a interest in Greek Mythology (age of 11), and I would suggest the name none other like Thanatos. It is this name I would give the moon P4 because he was the personification of death, while Hades was the god the underworld where all the dead live the rest of their lives. Their is a relationship between the two beings. He delivers the dead to the Underworld sometimes and also when near, people can sense death or have some kind of death instinct. His Roman counterpart Mors would also be a name I would choose.

  400. Jesse B-L -  July 25, 2011 - 2:31 pm

    I like Cerberus, although I think that “Tantalus” would be an appropriate name as well since the fruit and drink of planethood is so near (physically in Uranus, and actually in the dwarf’s recently demoted status).

  401. Ben Fix -  July 25, 2011 - 2:26 pm

    Sisyphus. Meaning: “Sisyphean”, endless and unavailing, as labor or a task.

    Once king of Corinth convicted to Hades by Zeus punished to roll a boulder uphill constant that ever tumbles downward once nearing the hill’s peak for revealing Zeus’ suspected identify. Sighted by chance, wrapped as a Eagle bearing a maiden away, abducted daughter of the river god Asopus. The stolen nymph daughter of Asopus, Aegina would become mother of Aeacus latter one of the three judges of Hades.

    Sisyphus had also trick the god of death Thanatos sent by Zeus, however the king chained the deity thus prevented death to any individual until Ares intervene out of his own outrage when his foes survived death and war.
    In his death in one tale also persuaded Persephone to return to the living world and scold his wife for not giving him a fit burial. But the king’s spirit refused to return back to the Underworld till he was forced back.

  402. Leah Smith -  July 25, 2011 - 2:14 pm

    On second thought, add Lethe to good names…

  404. Brian -  July 25, 2011 - 2:09 pm

    Gaea…creator of the earth and queen of living…..grandmother of the gods………or Hecate whom is the god of magic, witchcraft, and ghosts

    Through I like Lethe, but consider these too.

  405. ani -  July 25, 2011 - 2:09 pm

    Seems to me that they are on a rock band kick – Charon, Hydra, (Stevie) Nix, Styx, why not keep with that and rename P4 REO?

  406. allah -  July 25, 2011 - 2:04 pm

    we should name it the “korean”

  407. Kaitlin -  July 25, 2011 - 2:03 pm

    Proserpine (Persephone) would be nice seeing as she was the wife of Pluto. Although Cerberus is also a good name because it guards the gates of Hades.

  408. Cain -  July 25, 2011 - 1:43 pm

    Cerberus seems to be a reasonable conclusion, but Tartarus, being the dark prison in the underworld, would be my decision.
    Or It could be named sisyphus forced to roll a huge bolder up a hill forever only to watch it fall back to where it started.

  409. John -  July 25, 2011 - 1:43 pm

    I agree with Maria Mediarito. Lethe sounds to be a very fitting name for a satellite that has been in hiding so long.

  410. Rick P -  July 25, 2011 - 1:41 pm

    Very interesting and creative people have responded to this request. However, the suggestion of “Erebus” that was made earlier is certainly the most logical and appropriate choice. Given that Phobos and Deimos are moons for Mars and they are children of Aries (the Greek God Equivalent of Mars). Plus the other solar system examples that could be made here, a strong precedent has been set for this type of naming. The idea that Nix (Nyx was taken) should have her sibling and mate makes perfect sense. These two (2) gods share a lot with the underworld and Erebus will fit nicely into the mix of Pluto moons. Erebus should be elected as the name for this newly discovered moon, unless Stephen Colbert has his fan base vote for the moon to be named after him (lol).

  411. Jeff -  July 25, 2011 - 1:40 pm

    I think that it is a pity the moons were not named, Donald, Mickey, and Goofy. I guess finding this fourth moon would have made good arguments of Minnie versus Daisy….

  412. Gabby -  July 25, 2011 - 1:37 pm

    I would like to suggest Acheron,which means “river of woe”. It is a river in the underworld. I also support Maria Mediarito’s suggestion “Lethe”.

  413. Nscorz -  July 25, 2011 - 1:35 pm


    Then again it’d be better if another moon was named Charybdis….

  414. Leah Smith -  July 25, 2011 - 1:21 pm

    Cerberus is good

    Persephone is not good…
    She’s not part of the underworld always….

    Stick with Greek or Roman names, people.

    How about Thanatos, god of death????

  416. Book Beater -  July 25, 2011 - 1:01 pm

    Just plain “Bill” sounds good to me.

  423. cml -  July 25, 2011 - 12:33 pm

    While I like the “Persephone” idea (she is married to “Hades” -Greek, “Pluto” -Roman and a moon could be said to be married to its planet), I like the reasoning Maria Mediarito had for her suggestion “Lethe”. It’s up at the top if you want to read it. And whoever it was that suggested “Zues”, I would like to point out that we’ve already named a planet in our solar system “Zues”. “Jupiter” is the Roman name for “Zues”. I doubt they would want to call two celestial bodies in the same solar system the same person (even though it is a different name). Let’s save “Zues” for a supernova or a celestial storm or something that more represents the “King of the Gods” in mythology.

  424. randominity -  July 25, 2011 - 12:33 pm

    What about “Empousa”? The empousai were daemons (demons) of greek origin, having flaming hair and mismatched legs; one of bronze and the other of a donkey. Other than that, they looked like beautiful women. They would lure handsome young men into whatever sort of “lair” they had, where they would feast on the flesh of thier prey, drink their blood, and occasionally eat a bone or two.
    I think this is just morbid and gloomy enough to continue the “Pluto” theme. If not, I believe the 4th moon should be named after a daemon or monster, rather than yet another god/goddess or whatnot.

  425. Deryn -  July 25, 2011 - 12:28 pm

    Definately Cerberus.

  426. Dee -  July 25, 2011 - 12:25 pm

  434. Morgan Caola -  July 25, 2011 - 12:01 pm

    I think you should either call it “Thanatos” or “Hymnos.” Thanatos is the Greek personification of death, and Hymnos is the Greek personification of sleep. They are the twin sons of Nyx.

  443. dean -  July 25, 2011 - 11:44 am

    if the planet is named pluto it’s only obvious that we should have a Mickey up there somewhere too.

  444. KD -  July 25, 2011 - 11:41 am

    Lethe seems perfect to me. I would want to drink from it to forget my sorrows… maybe it will help Pluto forget His fall in rank.

    aidos kyneê cap of invisibility , a cyclops gift to use in battle, for pluto to use.

  447. Brittany -  July 25, 2011 - 11:31 am

    Cerberus because he gaurdes the gates of hell, this moon being the outermost moon of pluto, it is gaurding pluto. also, charon is the ferryman of the river styx so its quite fitting (keeping the under world theme).

  448. KJ -  July 25, 2011 - 11:25 am

    While not a figure, the river of forgetfulness itself would be an interesting choice: “Lethe”.

    For a figure, “Megaera” (one of the Erinyes, ministers of justice) would be a nice alternative.

  449. Elia -  July 25, 2011 - 11:25 am

    I suggest the name Morta after one of the three fates in Roman mythology. She was the one who cut the thread of life and chose the manner of a person’s death.

  450. Aaron -  July 25, 2011 - 11:15 am

    Just to throw another option out there, Morpheus. He was the god of sleep and dreams, which is kind of fitting for a moon that is located so far away in the dark.

    Erobus since there is already a moon named after Nyx. Erobus and Nyx worked side by side

  455. Cheryl -  July 25, 2011 - 10:57 am

    Since I have a very rare genetic neurological disease called CEREBELLAR ATAXIA, I have chosen:
    CERBERUS Κερβερος m Greek Mythology (Latinized)
    Latinized form of the Greek Κερβερος (Kerberos), which possibly meant “demon of the pit”… [more]

  456. reborn -  July 25, 2011 - 10:45 am

    hm.. can i ask what is the characteristic of that moon? and name it in accordance to its characteristic so as easy to identify since pluto has been demoted as a dwarf star or planet ;) bryx would be nice ^_^ it has no correlation i just thought what about bryx

  457. Zalinka -  July 25, 2011 - 10:36 am

    Considering the fact that all of Pluto’s other moons are named after mythological beings related to the Greek afterlife, the most sensible names would be either Styx or Hades. The Styx being the river of lost dreams that Charon ferries the dead souls across, and Hades being Lord of the underworld.

  458. AZN -  July 25, 2011 - 10:35 am

    Clotho-weaving time as we see it, whether it be beginning or end, this planet is necessity of life. is this moon older then the “first” moon discovered?? Psychology and weaving the most inner fabrics of our minds, we have to ask ourselves do we accept change through life and death or or do we stay in fear of our own hades and not accept a daughter of something right, our earth n moons?

  459. TimP -  July 25, 2011 - 10:30 am

    A constellation called Cerberus? There is no such thing! Look up the list of 88 constellation names…

  468. Tim Gale -  July 25, 2011 - 10:03 am

    Thanatos. As described by Wikipedia, this god was “often referred to but rarely appearing in person”. With that kind of description it seems to characterize this moon that we can’t often see.

    Proserpina — Pluto’s wife and the goddess of Springtime

  470. Kimmy -  July 25, 2011 - 9:51 am

    Persephone, because she is Hades’ (Pluto’s) wife. Therefore, it would be right for Pluto to have a moon named “Persephone”.

    But Hypnos, is also a good name. Because I think, I’m not really sure, he is the god of sleep. So, if they discover a 5th moon, then they could name that 5th moon “Hypnos.”

    But overall in conclusion, I think Persephone would be a good name for the 4th moon. Because it was believed that when Hades’ (Pluto’s) wife was near, he would usually be calmer. So Persephone should probably be the name!

  471. #1 Skillet Fan -  July 25, 2011 - 9:46 am

    Does it have to be from greek or roman mythology? What about Jangofett or Chewbaca?

  472. Danie Manos -  July 25, 2011 - 9:45 am

    “Prosepina”, Pluto’s wife.

  473. amrita -  July 25, 2011 - 9:43 am

    Most of my suggestions are taken, but I don’t think this is suggested yet. This is not really keeping up with the underworld theme, but is on par with the death theme: MORTA (ATROPOS in Greek), one of the three goddess of fate that cut the string of life, thus bringing death.

  474. aubrey -  July 25, 2011 - 9:24 am

    Let’s just call the damn thing Bob.

  478. Kelly -  July 25, 2011 - 9:15 am

    Styx, Cerberus, Lethe, Cocytus (also spelled Kokytos), Asphodel, Proserpina (also known as Persephone, or Kore), Alecto, Megaera, Tisiphone, Thanatos… There are dozens of names associated with the Underworld in Greco-Roman mythology.

  479. Rick -  July 25, 2011 - 9:13 am

    Since Cerberus has been used so frequently already, maybe Fluffy, like the 3 headed dog in Harry Potter.

  480. James -  July 25, 2011 - 9:13 am

    Bes, the Egyptian god of dwarves

  482. Joshua -  July 25, 2011 - 9:10 am

    The moon should be named Allecto, one of the three furies. The names is fitting because her mother is Nyx and her father is Tartarus, or Erebus. Some sources also say that Allecto could be the daughter of Pluto, or Hades, and Persephone. Allecto’s name means endless and unceasing and was charged, along with her two sisters, with a responsibility to maintain order using punishment in the Underworld. Comment if you think Allecto should be the name of Pluto’s fourth moon.

  483. Jeremiah Depta -  July 25, 2011 - 9:05 am


    It should be Persephone, without a doubt. Persephone was innocent and abducted. The body was just discovered and probably “abducted” by Pluto’s gravity. It’s association with spring represent’s NASA’s new beginning. Besides, Pluto needs a queen.

  484. Greg Sippel -  July 25, 2011 - 8:47 am

    Ctesippus – one of the wooers of Odysseus. And like the planet Pluto who’s first two letters represent Percival Lowell. The first 2 letters of Ctesippus; for Clyde Tombaugh. Who’s cremated remains are aboard New Horizons which will arrive near Pluto in July, 2015.

  485. Briana -  July 25, 2011 - 8:37 am


  486. Betsy -  July 25, 2011 - 8:24 am

    Why not Proserpina? That’s the name of Pluto’s wife in Roman mythology. Or how about the Greek version, Persephone?

  487. Baxter -  July 25, 2011 - 8:21 am

    Lex, as in Latin for law.

  488. Heather -  July 25, 2011 - 8:04 am

    Persephone should be next to lighten the evil around Pluto. Although her story is depressing it has a hopeful beginning with the creation of spring.

  489. Space -  July 25, 2011 - 8:02 am

    I’ve a question… How much of this actually helps in determining the name of this moon?
    May I suggest Nike, the Greek goddess of victory and diving?

  490. Matthew Copus -  July 25, 2011 - 7:58 am

    “Kore” Another name for Persephone who was abducted by Pluto and brought to the underworld.

  491. Zane Omega -  July 25, 2011 - 7:55 am

    I think the new moon should be “Cerberus”.

  492. Serina Sanchez -  July 25, 2011 - 7:52 am

    Defenitely ‘Persehone’, after Hade’s wife.

  493. Mel -  July 25, 2011 - 7:51 am

    Why not call it Hades? Since that eara seems to be named after things he is associated with, we should put him in thier.

  494. Bart Baird -  July 25, 2011 - 7:47 am


  495. Delaney -  July 25, 2011 - 7:43 am

    I think the new moon should be named Erebos because He is the god of darkness and shadow and pluto means Hades and he is God of darkness.

  496. Julia DuPree -  July 25, 2011 - 7:42 am

    Why not Obol? (Or a variation thereof.) If the moon is so tiny, perhaps it is just a “coin” in the cosmos.

  497. Book Beater -  July 25, 2011 - 7:41 am

    I’m not sure how the Hydra got in to the mix but I thought Cerberus would be the obvious connection.

    Morpheus – God of sleep/dreams

  499. Meredith -  July 25, 2011 - 7:38 am

    Proserpina or Persephone, the first being Roman and the second Greek. Persephone is the goddess of the underworld held captive by Hades(Pluto), just as moons are held captive by their planet’s gravitational field.

  500. Puggle -  July 25, 2011 - 7:37 am

    Too easy – it should be named “Hypnos”: the god of sleep. Nyx is the mother of Hypnos. If they find another moon, or a nearby dwarf-planet, they could name it “Thanatos” – the twin of Hypnos.

  501. Galena Krystine -  July 25, 2011 - 7:37 am

    Since it’s got kind of a dark theme going on there, I think it should be something like “Keres”- After the Fates of Death.
    Or maybe even after Erebos, primordial god of darkness and consort of Nyx.

  502. LEW -  July 25, 2011 - 7:34 am

    I vote for “Cerberus” (the three-headed guard dog of the gates to the Underworld) to go with the multi-headed theme of Hydra and the more general Underworld theme of Pluto and Charon and Nix.

  503. vyking -  July 25, 2011 - 7:30 am

    In sticking with the underworld theme, I’d have to suggest “Cerberus”, the three headed dog guarding the gates of the underworld and coincidentally the sibling of the Hydra. Hopefully they haven’t already named some other celestial body the same.

  504. dither -  July 25, 2011 - 7:27 am

    Charon was the ferryman across the river Acheron, not the river Styx. Common mistake. I think I’d suggest the name “Acheron” for the moon, so it could be next to Charon and maybe *then* people will stop confusing the two.

    What do you think? It goes with the Underworld theme that already exists, with the personification of darkness (Nyx), the ferryman (Charon), and the keeper of the dead (Hades/Pluto). Hydra was a guardian to the entrance of the Underworld at the lake of Lerna.

  505. Phillip -  July 25, 2011 - 7:27 am

    Cerberus is fitting if it’s not being used. I personally prefer objects consistently being named after Greek/Roman mythology.
    I’ve never understood the naming of Quaoar.

  506. Aeryn -  July 25, 2011 - 7:25 am

    Hypnos would have been cool. Pity we already gave that one to an asteroid. Maybe take a leaf from the book of Nix and call it Hipnos?

  507. Elma Corrin -  July 25, 2011 - 7:24 am

    I think the new moon shud be called Pluto Minor since it is a moon beside Pluto. This would show people how the moon is small.

  509. Larry Norman -  July 25, 2011 - 7:17 am

    A mysterious underworld demon. He was the father of Hades cattleman Menoetes.


    An underworld nymph. She was turned to dust by Persephone; her remains were then turned into a mint plant by the god Hades, who loved her.

  514. Garrett H. -  July 25, 2011 - 6:59 am

    In keeping with the Plutonian (Hades) nomenclature and makeup, why not Minos? He was the king of Crete who eventually became one of the three judges of death.

    Or how about Virgil? According to Edith Hamilton, he’s the Roman poet who described Hades with the most lurid zest.

  515. Joseph -  July 25, 2011 - 6:58 am

  520. Marc -  July 25, 2011 - 6:44 am

    Two possibilities:
    “Veneratio” – reputed to be the son of Pluto without a mother.
    “Avernus” – a gate of the underworld

  521. Ed Underfinger -  July 25, 2011 - 6:43 am

    “Cerebrus”- The mythological 3-headed dog guarding the gate of Hades.

  522. KLB -  July 25, 2011 - 6:41 am

  523. Bob Lindsey -  July 25, 2011 - 6:38 am

    As this moon is very small (dubbed mini-moon), and around a very small “former planet”, I propose the name “Aiolos”, which in Greek mythology means quick moving, and nimble! Thanks! Bob

  524. Jen -  July 25, 2011 - 6:38 am

    Persephone (queen of the Underworld)…:)

  525. Lindsey -  July 25, 2011 - 6:35 am

    Perhaps it could be named Hades, or maybe Styx, to keep with tradition, but Erebos is also an option.

  526. Samuel Cooler -  July 25, 2011 - 6:35 am

    MORPHEUS was the leader of the Oneiroi, the gods or spirits (daimones) of dreams. He manifested himself in the dreams of kings and rulers in the likeness of men as a messenger of the gods.

    Morpheus was probably equated with the Dream-Spirit which Zeus sent to visit Agamemnon in the Iliad (see the Oneiroi page).

  527. Eva -  July 25, 2011 - 6:31 am

    i think it should b Cerberus, protector of the underworld.

  528. C.B. -  July 25, 2011 - 6:28 am

    In keeping with the Greek/Roman tradition, I think the satellite should be named Athena who was the goddess of wisdom/knowledge. She was the daughter of Zeus (Jupiter)

  529. Chhavi Breja -  July 25, 2011 - 6:26 am

    In keeping with the Greek/Roman tradition, I think the satellite should be named Athena who was the goddess of wisdom/knowledge. She was the daughter of Zeus (Jupiter) and I don’t think her name is taken. Her roman counterpart is called Minerva, which is also a very apt name.

  530. Pragya Tiwari -  July 25, 2011 - 6:09 am

    Priam – was the King of Troy during Trojan War, and the youngest son of Laomedon (in Greek Mythology).

  531. Hil -  July 25, 2011 - 6:05 am

    In keeping with the underworld theme, I would think Persephone might work.

  532. Mohammad -  July 25, 2011 - 6:01 am

    Heracle would be nice as two moons show a Mother-Son relationship (Nyx and Charon), Heracle would be nice as it would give a Slayer-Slain relationship (Heracle and Hydra).

  533. Kathleen Bryant -  July 25, 2011 - 6:00 am

    Because Charon, Hydra, Pluto, and Nyx are all somewhat related to darkness, death, and the underworld, I’d suggest two names in keeping with the Hades motif. The first is Persephone, the unwilling wife of Hades whose absence from the earth four months a year brings winter. Alternatively, Cerberus would also be appropriate as the three-headed dog who keeps watch over the gates of the underworld.

  534. Zachariah -  July 25, 2011 - 5:54 am

    In Greek mythology Telemachus was the son of Odysseus in Homer’s Odyssey. Telemachus’ name means “far from battle” and it is fitting that this new moon be named as such in this time when there are so many battles being fought on planet Earth and this new moon is so far away.

  544. Matt Roberts -  July 25, 2011 - 5:37 am

    Souda or Suda. It means “fortress” or “stronghold”. Sounds good to me! It’s an ancient encyclopedia from sometime in the 10th century, which Homer and quite a few others are noted on. Should be Greek enough.

  545. Frode -  July 25, 2011 - 5:36 am

    Since the largest moon is named after Charon, the ferryman transporting the souls of the deceased to the land of the dead, why not name this one Atropos, after the Moirae who cut a person’s life-thread when their time was up, and chose how they died?

    Alternatively they could rename Nix and Hydra, and have all three outer moons named after the three Moirae. From inner to outer:
    Nix = Clotho, the spinner of the life-thread
    P4 = Lachesis, who measured the life-thread
    Hydra = Atropos, the cutter of the life-thread

    But I guess that’s less likely to happen :)

    It is wrong to say that naming of planets and other celestial objects traced back to Babylonians. Scientists, world-wide, do not recognise the Astronomical contributions made by Hindus. Let us not forget Aryabhatta and Bhaskara.

    Why not they mention Hindus while they quote Greeks and Romans? The entire solar system, even the galaxies are named after Hindu Gods and Godesses by the Hindus several centuries before.

  549. Edward -  July 25, 2011 - 5:27 am

    It should be called Helots, an unfree population group that formed the main population of Laconiaa (capital Sparta). These people were tied to the land, as this moon it to pluto.

  550. Lauren -  July 25, 2011 - 5:26 am


    Charon is an alternate name for Styx, but sounds a little less ominous. It stays with the mythological theme, but is admittedly the name of an object instead of a god or creature.

  551. john -  July 25, 2011 - 5:20 am

  564. Danny Badawy -  July 25, 2011 - 4:26 am

    I suggest the name: Mors.

    In ancient Roman myth, Mors is the personification of ‘Death’ equivalent to the Greek Thánatos.
    In Roman Mythology, Mors is shown as a servant to Pluto, ending the life of a person after the thread of their life has been cut and escorting the dead person’s soul, or shade, down to the underworld’s gate.

    As a small moon of Pluto, P4 (Mors) looks like a servant to Pluto.

  565. ATTAKowl -  July 25, 2011 - 4:23 am

  566. Wray Dumont -  July 25, 2011 - 4:22 am

    How about the Greek God “Lêthô”, or “Lanthanô”, or “Lelathon”, meaning “to escape notice,” “move unseen” or “go unobserved.” He was the younger Titan god of air and a stealthy hunter. Lêthô seems like the most appropriate moniker since it has been orbiting Pluto for so long and despite all the advancements in our planet & star searching methods, it has not been detected until now. Lêthô would be my first choice since it’s short & sweet. It’s not too plain (with all those accents) but simple, and a name people will remember easily.

  567. Erebus -  July 25, 2011 - 4:22 am

    In Greek mythology, Erebus ( /ˈɛrəbəs/), also Erebos (Ancient Greek: Ἔρεβος, “deep darkness, shadow”), was the son of a primordial god, Chaos, and represented the personification of darkness.
    Erebus married his sister Nyx (goddess of the night) and their offspring include: Aether, Cer, Hemera, Charon, the Hesperides, Hypnos, the Moirae, Momus, Nemesis, Oneiroi, Phlegethon, Styx, and Thanatos.
    In Greek literature the name Erebus is also used to refer to a region of the Underworld where the dead had to pass immediately after dying, and is sometimes used interchangeably with Tartarus.

    Furthermore: If there are more moons around Pluto, then I suggest the contingency plan to name them: a) Orphnaeus [Orphnæus], b) Aethon [Æthon], c) Nycteus and d) Alastor, … after the dark horses of Pluto.

  573. Nick -  July 25, 2011 - 3:52 am

    call it cerberus

  574. Jez -  July 25, 2011 - 3:52 am

    They should call it págos which is ice in greek!

  575. Nick -  July 25, 2011 - 3:30 am

    cerberus the three headed dog of pluto

  576. Ignacio Elia -  July 25, 2011 - 3:27 am

    Pluto and its moons are named after darkness and death. Pluto is the greek god Hades (or at least, that’s the common consensus) was both grandson and great grandson (since Gaia and Uranus were both mother and son and wife and husband) of Gaia (Earth), Nyx is the representation of the Night, Charon (Kharon) is the ferryman of the dead over the river Styx, and Hydra is the daughter of Typhon (the most deadly monster of Greek mythology, often called “Father of all monsters”, last son of Gaia) and Echidna (“Mother of All Monsters”).

    So, Hydra is a cousin in a 2nd degree of Hades (the planet Pluto) and Nyx (the moon Nix) is the great grand aunt of Hades and grand aunt of Hydra. Family relation ends there.
    Kharon (the moon Charon) is the ferryman of the dead.

    It cannot be Erebus (Erebos), because it did not have a body. Same with Tartarus (Tartaros).
    If it was called Acheron (Akheron), it should have its place exchanged with Charon. It cannot be either. Same goes with Cerberus (Kerberos) and Hermes Chthonius (Khthonios).

    Hecate (Hekate), the goddess of magic, necromancy and the haunting ghosts of the dead. She who issued forth from the underworld with a train of torch-bearing Lampades, demonic Lamiae, ghosts and hell-hounds. Hecate was the minister of Persephone. That would be an interesting name.

    Hypnus (Hypnos), the god of sleep who dwelt in a silent realm on the borders of Hades. He issued forth from the underworld with his mother Nyx the Night. That’s a very interesting name too.

    Lethe, the goddess of the underworld river of oblivion. The souls of the dead tasted her waters to forget their former lives. That too is a great name.

    I would propose the name “Lethe”, since it is between Hydra (the killing monster) and Nix (the night the dead have to go through), thus allowing the ones who pass from life to death to drink from the waters of oblivion before being ferried by Charon to the house of Pluto.

    Persephone. She was his Hades’ wife and it seems appropriate for one of his moons to be named for her

  579. Ramamurthi -  July 25, 2011 - 3:01 am

    In the universe many nebulas lived we are not recognised ,isugest so easy recoginised it P4 .T.Q.

  580. Janalyn -  July 25, 2011 - 2:56 am

    CERBERUS the three-headed dog seems a natural following choice. Or PROSERPINA, Pluto’s wife, rarely seen by us mortals on Earth.

  581. Hillary -  July 25, 2011 - 2:55 am

    It’s obvious. Cerberus. ;)

  582. Emma -  July 25, 2011 - 2:52 am

    ‘Deimos’ means terror in Greek mythology. I think it’s a suitable name.

  583. Clint Bechus -  July 25, 2011 - 2:38 am

    I think this new moon should be called Furrina.

    As Pluto was downgraded from a mighty planet to a dwarf, I thought Furrina would be appropriate as she was once highly regarded, but now scientists can’t even decide what role she played.

    She is all but forgotten.

    Some suggest she was a water goddess, others suggest theft and a few suggest she was similar to the furies. For a moon surrounding an icy planet who had its title stolen from it. Water, theft and anger seem appropriate.

    I think that by naming her as one of the moons we would be bringing a rightful God, and a rightful planet, back into the limelight.

  584. Dr Shailesh G -  July 25, 2011 - 2:34 am

    Varonus, Varunus, Varunansh, Varunkhand, Varuni,
    as in Hindu ancient science not mythology this planet was already discovered and was named Varun.. the moon, it’s part can be named accortdingly. In the order in the above line. Just for information all the boundries of the universe was already known to Indian seers(read scientists and thinkers), we already have huge traesure of astrophysical, astronomical and astrological knowledge that was discoevered whn there was no human in other parts of world or was primitive only.
    I think christening a Hindu name which was named some 3-4000 yrs back would do some justice and also would be novelty to the nomenclature till now by NASA.
    The sanskrit name has also been greekened by me already..

  585. Logan -  July 25, 2011 - 2:33 am

    Why not call it Cerberus after the three headed dog that guards the entrance to the underworld, or Lethe, Styx, Cocytus, Phlegethon, or Acheron, the five rivers of the underworld. Or maybe Erebus, the father of Charon.

  586. Edwin Tan -  July 25, 2011 - 2:30 am


  587. lauren stewart -  July 25, 2011 - 2:23 am


    Pluto is named for the God of the underworld. If its moons are named after the ferryman of the underworld, the goddess of darkness and night (two thing often associated with death and the underworld), and the fearsome Hydra it its seems obvious to me that he next moon would be named Cerberus.

    In Greek mythology he is the three headed dog that guards the underworld linking him to both Pluto and Charon, and vaguely to Nix as well. He also ties Hydra better in with the others as slaying the Hydra was Hercules’ second task and capturing Cerberus alive was his twelfth task.

  588. eee -  July 25, 2011 - 2:15 am

    Oneiroi would be nice, I think.

  589. Keelan -  July 25, 2011 - 2:08 am

    Styx would be cool, to rhyme with Nix and to keep the relation to Charon. Or perhaps Cerberus if that isn’t already a name of a star. Though Cerberus is a powerful name and sounds more appropriate for a planet…perhaps with three moons.

  590. William Bagnall -  July 25, 2011 - 2:01 am

    The name “Arges” would be an intriguing name for a moon, as it is the third and brightest cyclopes child of Gaia.

  591. Eesgooshee -  July 25, 2011 - 2:00 am

    Cerberus? It’s already the name of an asteroid, a constellation and an albedo feature (dark spot) on Mars, but it seems appropriate enough.

  592. manikandan -  July 25, 2011 - 1:52 am

    The two remaining moons, Nix and Hydra are named in part for their initials NH, a reference to the New Horizons robotic spacecraft mission; or perhaps the names suggest the watchful eye the two keep over Pluto.
    is correct

  593. Yasir Arfat -  July 25, 2011 - 1:43 am

    i suggest the name of fourth moon of pluto “xyna”
    i derived it from ‘xana’. The origin of the Asturian word xana is unclear, though some scholars see it as a derivation from the Latin name for the goddess Diana.

  594. Geetha -  July 25, 2011 - 1:37 am

    The name can be “Zeus”

  595. Sammy -  July 25, 2011 - 1:26 am

    It should be named “Stormfront.”

  596. Chad -  July 25, 2011 - 1:20 am

    I suggest either:

    Persephone- The women of which was stolen away by Hades

    Minos- For the King who has been deemed to pass judgement to the tortured souls in Hades

    Cerberus: For the Three-headed beast that guarded the gates of the Underworld .

    Elysium: For the fields of hero’s and the triumphant souls who dwell within the underworld.

  597. Alex Gmonz -  July 25, 2011 - 1:19 am

    I reckon it should be called “Lunara” as Luna means moon and why I say Lunara because the style of newly foundd objects have very odd names.

  598. Tyler -  July 25, 2011 - 1:17 am

    Cerberus, guardian of Pluto’s domain.

  599. vicky g -  July 25, 2011 - 1:13 am

    Persephone, after the wife of Hades.

  600. Sherry Smith -  July 25, 2011 - 1:09 am

    AETHER was “the son of Erebus and Nyx. He is the personification
    of the space, the upper sky, and heaven, and is the elemental
    god of the ‘Bright, Glowing, Upper Air.’ He is the pure upper
    air that the gods breathe, as opposed to the normal air
    mortals breathe.”

    sugest venpound whch cumz frm venetia & 5pound she receive frm his grndpa!!

  602. George Xu -  July 25, 2011 - 1:04 am

    Cerberus, the three-headed-dog that guards the gate of the underworld

  603. George Xu -  July 25, 2011 - 1:03 am

    I think to keep up with the tradition of naming Pluto’s moons with mythological characters, I give the name Cerberus, the three-headed-dog which guards the gate of the underworld.

  604. Manny Armstrong -  July 25, 2011 - 12:56 am

    Sorry that would be anywhere =D

  605. Manny Armstrong -  July 25, 2011 - 12:53 am

    Wow is this true?
    Because I’m really into space and I don’t see the 4th moon anyways.

  606. Elina -  July 25, 2011 - 12:52 am

    sorry what i wrote before but plata should be the name because pluto has gained the planet and plata is closed to pluto the name
    vote for my name

  607. plata -  July 25, 2011 - 12:50 am

    Plata should be called that because pluto has gained the new planet and not neptune has gained it and plus pata is close to pluto

  608. Richard Rogers -  July 25, 2011 - 12:41 am

    I think Persephone would be an obvious choice.

  609. Narcisus -  July 25, 2011 - 12:29 am


  610. Narcisus -  July 25, 2011 - 12:28 am

    i may have not spelled the name right. the name came from a greek story in which there was a handsome and then he fell in love with himself when looking at a clear spring water pond and so he died because he did nothing but look at himself. and so a goddess turned him into a flower, but then the pond talked to the goddess and became a saltwater pond because it told the goddess that in the man’s eyes she saw herself

  611. Megan Taylor -  July 25, 2011 - 12:26 am

    I think Persephone would be a suiting name given the theme of the Underworld surrounding Pluto.

  612. Age -  July 25, 2011 - 12:25 am

    or Erebus !

  613. Cameron Bergerac -  July 25, 2011 - 12:22 am

    I’m probably not the first to suggest this, but what about “Cerberus” – the three headed dog that guarded the gates of hell.
    Fitting – especially if it’s Pluto’s outermost moon.

  614. Vishnu -  July 25, 2011 - 12:22 am

    Viduus – Roman god who separated the soul and the body after death.

    To keep with the whole Pluto theme.

  615. naghihamekasi -  July 25, 2011 - 12:17 am

    I think we should name it :Apollonius
    My reasons:
    He was Greek
    He was an astronomer
    The name implies Greek mythology i.e APOLLO
    It sounds like a related word to PLUTO!
    And among geometers he truly stands out as a god!!
    hope you are convinced.

  616. Kent Ochse -  July 25, 2011 - 12:16 am

    Soteria, personification of safety and the deliverance from harm. This name is fitting because this moon is so far away from the sun and Earth, thus personifying safety and distance from the harmful effects of our part of the solar system.

  617. Dennis -  July 25, 2011 - 12:16 am

    Cerberus would be an appropriate name for the newly discovered satellite of Pluto.

  618. Age -  July 25, 2011 - 12:15 am


  619. Orrin Hicks -  July 25, 2011 - 12:12 am

    Kerberos, the guardian to the gates of the underworld.

  620. joshua ashade -  July 25, 2011 - 12:10 am

    i suggest it should be named after osiris, the Egyptians’ gods.Osiris is the
    god of the

    Husband of

  621. Greg Dalberg -  July 25, 2011 - 12:03 am

    Hun-Came (chief Mayan death god)

  622. Binaya Basnet -  July 24, 2011 - 11:57 pm

    Styx after the river styx

  623. Jimmy Currin -  July 24, 2011 - 11:54 pm

    What about Dis?

  624. Josh -  July 24, 2011 - 11:53 pm

    I say “Erebos.” It fits right in with the Roman Mythological naming of the moons brothers and sisters. Erebos, the Roman god and personification of Darkness, may also be a fitting name, given that the moon has just been discovered, way out in the dark regions of the Solar System.

  625. yash -  July 24, 2011 - 11:41 pm

    I would name it as ‘Plumoon”

  626. Maria Mediarito -  July 24, 2011 - 11:37 pm

    Hm… I’ve had quite an interest to Mythology as well as that Venetia Burney (Only, I’m just 12.)
    I’d like to propose the name “Lethe”. Which is one of the rivers in the Underworld, which the dead bathe in so that may ‘be cleansed of their mortal memories” and be reborn or resurrected. If my memory does not fail me, “Lethe” means concealment. To “conceal” something is to hide it, and this 4th moon has only been discovered far later than the other 3 moons. So I suppose in some way, you could say “P4″ was in ‘hiding’.

  627. Bill Watson -  July 24, 2011 - 11:09 pm

    I don’t know how you can have Pluto and Charon without it.

  628. melissa -  July 24, 2011 - 11:08 pm


  629. Bill Watson -  July 24, 2011 - 11:07 pm

    Of course it should be cerberus.
