Iapetus

Iapetus was discovered by G. Cassini in 1672. Iapetus is the 2nd farthest moon from Saturn. Iapetus is one of the icy moons of Saturn. Iapetus is about as wide as California is long.

Iapetus is very much like Rhea, Enceladus, Dione, and Tethys except that it looks completely different. It looks half dark and half bright.
