Tethys
moon of Saturn · almost pure ice
8.62 AU from Earth
A moon 1,062 km across made almost entirely of water ice: its density, 0.98 g/cm³, is just under water's. Ithaca Chasma, a canyon up to 100 km wide and about 3 km deep, runs some 2,000 km across it, and the crater Odysseus is 445 km wide, more than two fifths of the moon's width.
- 1,062 km across · density 0.98 g/cm³, nearly pure ice
