Rhea

Rhea was discovered by G. Cassini in 1672. Rhea is the 5th farthest moon from Saturn.

Rhea is one of the icy moons. Rhea is about as wide as the state of California is long.

Rhea is has many craters and also has wispy white streaks across the surface. This moon looks very much like Dione, Enceladus, and Tethys, and is the biggest of the four of them.
