The Moons of Saturn. Saturn has 52 known satellites as of 2008, 7 of which were discovered by the Voyager spacecraft. The largest and most interesting is Titan, which is 3600 miles in diameter and 922,000 miles from Saturn. It is the only satellite to have a thick atmosphere, and a surprisingly dense one, too: 1.6 atmospheres.
