Odysseus is the largest crater on Saturn’s icy moon Tethys. It is 445 km across, more than 2/5 of the moon’s diameter, and is one of the largest craters in the Solar System.

Odysseus was discovered by Voyager 2 spacecraft on 1 September 1981 during its flyby of Saturn.

This view was taken by the Cassini spacecraft on Aug. 17, 2015, at a distance of about 28,000 miles (44,500 kilometers) from Tethys.
