Pluto’s known system of moons (NASA/ESA/M. Showalter)

Today marks seven months since the announcement of Pluto’s fifth moon and over a year and a half since the discovery of the one before that. But both moons still have letter-and-number designations, P5 and P4, respectively… not very imaginative, to say the least, and not really fitting into the pantheon of mythologically-named worlds in our Solar System.

Today, you can help change that.

According to the New Horizons research team, after the discovery of P4 in June 2011 it was decided to wait to see if any more moons were discovered in order to choose names that fit together as a pair, while a*lso following accepted IAU naming practices. Now, seven months after the announcement of P5, we think a decision is in order… and so does the P4/P5 Discovery Team at the SETI Institute.

"Hey, I can be democratic about this!"

“Hey, I can be democratic about all this!”

Today, SETI Senior Research Scientist Mark Showalter revealed a new poll site, Pluto Rocks, where visitors can place their votes on a selection of names for P4 and P5 — or even write in a suggestion of their own. In line with IAU convention these names are associated with the Greek and Roman mythology surrounding Pluto/Hades and his underworld-dwelling minions.

“In 1930, a little girl named Venetia Burney suggested that Clyde Tombaugh name his newly discovered planet ‘Pluto.’ Tombaugh liked the idea and the name stuck. I like to think that we are doing honor to Tombaugh’s legacy by now opening up the naming of Pluto’s two tiniest known moons to everyone.”

– Mark Showalter, SETI Institute

As of the time of this writing, the ongoing results look like this:

Results of Pluto Rocks voting as of Feb. 11, 2013 at 10 am EST (15:00 UT)

Results of Pluto Rocks voting as of Feb. 11, 2013 at 10 am EST (15:00 UT)

Do you like where the voting is headed? Are you hellishly opposed? Go place your vote now and make your opinion count in the naming of these two distant worlds!

(After all, New Horizons will be visiting Pluto in just under two and a half years, and she really should know how to greet the family.)

Voting ends at noon EST on Monday, February 25th, 2013.

The SETI team welcomes you to submit your vote every day, but only once per day so that voting is fair.

UPDATE: On Feb. 25, the final day of voting, the tally is looking like this:

PlutoRocks results as of Feb. 25, 2013 - Vulcan is in the lead, thanks to publicity from Mr. William Shatner

PlutoRocks results as of Feb. 25, 2013 – Vulcan is in the lead, thanks to publicity from Mr. William Shatner

Thanks in no small part to a bit of publicity on Twitter by Captain Kirk himself, Mr. William Shatner (and support by Leonard Nimoy) “Vulcan” has made the list and warped straight to the lead. Will SETI and the IAU honor such Trek fan support with an official designation? We shall soon find out…

I was thinking Cerberus for one name. I couldn’t think of another till I saw Styx. I like these names for the moons, and hope they’re picked.

Shootist February 11, 2013 at 4:09 PM

Cerberus and Styx

And if there is a 6th moon, Heracles. And a 7th, Persephone.

kkt February 11, 2013 at 7:29 PM

There’s a big asteroid called Persephone already. A Heracles too.

Shootist February 12, 2013 at 3:20 AM

Too much to expect mythological consistency, I suppose.

Ladislav Florián February 11, 2013 at 4:33 PM

P4: Styx
P5: ?????? (Gold Coin)

Tone Yvr February 11, 2013 at 4:43 PM

I agree with the comments below. I particularly like Cerberus because he’s a dog, albeit – unlike dear Pluto – he’s 3-headed and fierce :) And Styx, even tho’ it’s a river not a character, it is what Charon navigates … and does rhyme nicely with Nix.

Tone Yvr February 11, 2013 at 4:49 PM

I just discovered Orthrus, Cerberus’s brother – not on the list, but also a (rather nasty looking) dog.

TerryG February 11, 2013 at 5:57 PM

Potential names for Pluto’s neighbors…

Hmmm, it would seem that Goofy, Daffy, Porky, Wile E and Bugs have been inexplicably over looked.

Aqua4U February 11, 2013 at 5:57 PM

Clyde? (Tombaugh’s legacy)

Bob Sireno February 11, 2013 at 9:34 PM

Why not let corporations buy the naming rights? Let the powers that be decide who gets how much. I vote for Microsoft and Apple as the moon’s names.

bdlaacmm February 11, 2013 at 10:20 PM

Have they never heard of parallelism? We already have Charon (ferryman over the river Acheron). We should name the new moons Phlegyas (ferryman over the river Styx), and Geryon (“ferryman” over the Phlegethon waterfall, both names from Dante’s Inferno).

Domingo Fermin February 12, 2013 at 2:42 PM

ENLILTUS… that’s the name!!

Marco Stickman February 12, 2013 at 9:37 PM

Maybe a tiny bit off point, but, I am stuck on the fact that Pluto has 5 moons, yet for some reason, is denied the designation of, “Planet”…Other than the Sun, I believe every other body large enough to attract and retain satellites in our Solar System, is a Planet, but, Pluto is a “Kuiper-Belt-Object” with 5 moons.

I like Hypnos and Cerberus, but not together, they’ve no apparent association, or one I am totally missing. I wish there were more choices. Castor and Pollux?

David Krauss February 15, 2013 at 2:05 AM

Nah, many main belt asteroids have satellites. They aren’t necessarily attracted, they can be chipped off by impact.

First Emerison
Second Marcnutus

Jason Major February 13, 2013 at 6:06 AM

Thanks to a suggestion by Captain Kirk himself, Mr. William Shatner, “Vulcan” is now on the list!

ITSRUF February 13, 2013 at 6:38 AM

Since Pluto is named after a cartoon dog, I suggest Huey, Dewey, and Lewie — Mickey and Minnie, ect…

Sally Windsor February 13, 2013 at 7:09 AM

I think plutos moons should be called Arjun the 2nd and Oskar the 2nd.

Ben Miller February 14, 2013 at 5:09 PM

Why not Romulus? or Qo’noS? :)

Moo Cow February 18, 2013 at 4:34 AM

Alas, there is already a moon in our solar system named Romulus (as well as Remus).

I really think one should be named Proserpina, the Roman equivalent of Persephone. :)
