Distant Tethys

With just a bit of detail visible on its lit hemisphere, Tethys was imaged by Cassini-Huygens on 20 July 2004. A round feature, likely a large crater, can be seen near the boundary where day and night meet, at the bottom of the image. Dark markings are visible near the top.

The image was taken in visible light, with the Cassini-Huygens spacecraft narrow angle camera from a distance of 6.1 million kilometres from Tethys. The image scale is 37 kilometres per pixel. The image has been magnified by a factor of four to aid visibility.
