Tethys

Natural Satellites

Tethys is Saturn's fifth-largest moon, about 1,060 km across. Discovered by Giovanni Domenico Cassini in 1684, it is named for the Titan Tethys of Greek mythology. Its low density and surface spectroscopy indicate that it consists mainly of water ice with a small fraction of rock and dark material. The bright, heavily cratered surface includes Odysseus crater and the long Ithaca Chasma graben.
