Crater Odysseus on Saturn's moon Tethys

The eastern rim of the large crater Odysseus is visible along the terminator in this image of Saturn's moon Tethys. This enormous impact feature is the largest on Tethys, at approximately 450 kilometres across. The shadowy rim of another smaller crater can be seen at the bottom. Tethys is 1060 kilometres across.

This Cassini view shows principally the leading hemisphere of Tethys. The image was taken in visible light with the Cassini narrow-angle camera on 18 December 2004, at a distance of 1.7 million kilometres from Tethys. The image scale is about 10 kilometres per pixel. The image has been magnified by a factor of two and contrast enhanced to aid visibility.
