Images taken by the Hubble Space Telescope in 2011 and 2012 revealed two previously unknown moons of Pluto. So far, we have been calling them “P4” and “P5”, but the time has come to give them permanent names. If it were up to you, what would you choose?

By tradition, the names of Pluto’s moons come from Greek and Roman mythology, and are related to the ancient tales about Hades and the Underworld. 

Ground Rules: Feel free to come back, but please do not vote more than once per day, just so everybody gets a fair chance to make their opinion known. We will take your votes and suggestions into consideration when we propose the names for P4 and P5 to the International Astronomical Union (IAU). Voting ends at noon EST on Monday, February 25th, 2013.
