Pluto Moons

The fourth and fifth known moons of Pluto, discovered in 2011 and 2012, have been officially named Kerberos and Styx by the International Astronomical Union. Kerberos or Cerberus was the three-headed dog that guarded the entrance to the Underworld. Styx was the river across which the Underworld was found. Pluto's first moon, Charon, was named for the boatman who ferried souls across the Styx. Pluto may not be a planet, but it can still have moons. The New Horizons spacecraft is expected to encounter Pluto in 2015, in time for the IAU meeting in Honolulu.

INteresting idea to give name as three-headed dog. It's funny.

I thought Pluto's moon was named for Clyde Tombaugh's wife.
