The second-largest satellite of Saturn, 1527 km in diameter; also known as Saturn V. Rhea orbits Saturn in 4.518 days at a distance of 527 068 km. Its axial rotation period is the same as its orbital period. It was discovered in 1672 by G. D. Cassini. Rhea has an icy surface saturated with impact craters, the largest, Mamaldi, being 480 km across, and shows broad, elongated wispy features of unknown origin on its trailing hemisphere.

A genus of large, flightless birds, rheas (family Rheidae) are up to 1.7 m tall, with grey-brown plumage, long legs, and a long neck. They sometimes form flocks of 20 or more birds. They are herbivores, but also eat small animals. They occur only in South America. There are two species, the greater (R. americana) and lesser (R. pennata) rhea.
One of the major satellites of Saturn, with a radius of 764 km; mass 23.1 × 1020 kg; mean density 1240 kg/m3; visual albedo 0.7. It was discovered in 1672 by G. D. Cassini.
