True, but since Pluto isnt a planet, Charon isnt a moon (open floodgates!)
Not necessarily true - "moon" seems to be used for any body which orbits a larger one (see
http://en.wikipedia.org/wiki/Natural_satellite ).
On that note, I find it interesting that no one cares about how many moons we have - we have 240 known moons, some of them as small as 1km, and no one finds that strange...
