Odysseus Crater on Tethys, by Cassini


A huge impact created Odysseus Crater, which covers a large part of Saturn's moon Tethys in this Cassini spacecraft image.

Odysseus Crater is 450 kilometers (280 miles) across. This view looks toward the leading hemisphere of Tethys (1,062 kilometers, or 660 miles across). North on Tethys is up and rotated 3 degrees to the left.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 27, 2010. The view was obtained at a distance of approximately 703,000 kilometers (437,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 79 degrees. Image scale is 4 kilometers (2 miles) per pixel.
