Odysseus

Caption NASA:"The Cassini spacecraft provides a stunning view of the Odysseus impact basin on Tethys. The enormous basin is about 450 Km (approx. 280 miles) wide.
The medium-sized crater Melanthius is seen along the Terminator at lower left.
This view looks toward the Leading Hemisphere of Tethys. North is up.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 21, 2007. The view was obtained at a distance of approx. 211.000 Km (such as about 131000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 46°.
Image scale is 1 kilometer (0.6 mile) per pixel".
