It does blow my mind that we can spot a 30 mile wide object from that far away.
I like the idea of calling it Xenu. Then we can send all the Scientologists there.
Howsa 'bout we name one of them “Yuggoth”?
Heh! I remember that short story…
Just because I’m all giggly about having an inside scoop: A colleague of mine has been in email contact with Alan Stern, and he says that picking names might be a bit premature.
Recieving a preliminary designation like S/2005 P2 & S/2005 P3 is no guarantee that these things are real. They need to be monitored to confirm that they are actual objects orbiting Pluto.
Dante and Cerberus get my vote–Persephone, not so much.
How big are the moons–larger than Charon?
Amalthea was a nymph, at least in some stories. And a centaur is a huminoid (sorta, kinda, maybe?, well at least more huminoid then a three headed dog).
Much smaller, 30-100 miles in diameter according to the article. Also from the article:
So I think Dante, Virgil, Perceivil and Dracula (Dang!) are out.
Much smaller 30 to 100 mile diameters is what the article said.
How about Persephone and Hecate?
My bad. Thanks, all. 
Mythological names? But–but–but Dante is so cool-sounding! sniffles
Let’s hope so, I’m not holding my breath, however.
Problem with Persephone is that there’s already an asteroid with that name. They used up almost all the good Greek/Roman names on asteroids. If the IAU decides to declare 2003 UB313 (I refuse to call it Xena) a planet, my bet is that it will get called Cerberus, which is still available. I think they’ll go for something lesser-known for Pluto’s new moons.
In keeping with the rest of the planets, it would be more fitting to have a new planet named after another god/goddess. There must still be some god/goddess names left that haven’t been used on asteroids? They already wasted Juno, Ceres and Vesta on asteroids. It might be fun to switch to the Greek names and name the 10th planet Hades.
I still think Cerberus would be better suited to a moon of Pluto.
Orpheus and Eurydice are another possibility for the moons.
I’m of the firm opinion that using up all the good names on asteroids was a big mistake that needs to be undone right now. I think the IAU should declare that planets supercede moons, which supercede asteroids, and that any newly discovered body can be given the name of a body it supercedes, which must then be given a new designation. Who cares what asteroids are called anyway? Just give 'em all numbers! Just to prove the point, I think they should call the tenth planet “the Moon”!
If that doesn’t work, nuclear missiles should be sent up to demolish the asteroids, so that their valuable names can be reused. People have been predicting that we’ll someday mine the asteroids anyway. Why not mine them for names? Just think–we’ll be sending nukes into space to mine the heavens for deities. It’s almost poetic!
Pluto is Roman, so to be consistent use Proserpine rather than Persephone.
How about we ditch the name Charon, and call the moons of Pluto Cerberus A, Cerberus B, and Cerberus C? Or, if we keep the name Charon, we can call one of the moons Cerberus and the other Fluffy.
