Rhea was discovered by Giovanni Domenico Cassini in 1672.
Rhea is the second-largest moon of Saturn and the ninth largest moon in the
Solar System.
Rhea name is suggested by John Herschel on 1847. He suggested the names of the Titans, sisters and brothers of Cronos (the Greek Saturn), be used. Rhea in Greek mythology was the Titaness daughter.
This Rhea map is based on the Cassini and Voyager missions.
Rhea is an icy body with a density of about 1.236 g/cm3. This low density indicates that it is made of ~25% rock (density ~3.25 g/cm3) and ~75% water ice (density ~0.93 g/cm3). While Rhea is the ninth-largest moon, it is only the tenth-most-massive moon.
