Re: Large Satellites?

So how do you deal with the Pluto - Charon system?

Charon is spherical, and has half the diameter of Pluto (and about 1/8 the mass), making Pluto - Charon a binary system (much more so than Earth - Moon, for example). And the barycentre of Pluto - Charon lies WELL outside Pluto.
