Rhea

Rhea was discovered by G. Cassini in 1672. Rhea is the 5th farthest moon from Saturn. It is one of the icy moons, similar to the Galilean satellites. Rhea is about as wide as the state of California is long, with a width of 1500 km (1000 miles).

Rhea is heavily cratered but with wispy white streaks across the surface. In appearance, this moon looks very much like Dione, Enceladus, and Tethys, and is the biggest of the four.
