astroengine writes "The SETI Institute has launched a new website called "Pluto Rocks!" intended to gather a public vote on the names of Pluto's smallest, and most recently discovered, moons P4 and P5. Discovered in 2011 and 2012 by Hubble, the two dinky satellites have concerned scientists managing the NASA New Horizons probe that will flyby the Plutonian system in 2015 — the presence of small rocky bodies in Pluto orbit might mean there is a significant collision risk to the high velocity spacecraft. This sinister back story will surely influence the naming outcome of the two new moons, where all the suggestions on Pluto Rocks! are related to Greek and Roman mythological characters from the underworld (but you can also make your own suggestions). If you want to get involved, there's also a special SETI Institute G+ Hangout planned for 11 a.m. PT Monday where two of the P4/P5 discovery scientists will hold a Q&A session."
