Tethys

moon of Saturn · almost pure ice

8.64 AU from Earth

Tethys, drawn in ASCII characters

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.

Numbers that change with time are from 10 November 2026.
