The 450-kilometer (280-mile) wide Odysseus is a well-preserved example of an ancient multi-ringed impact basin. The outer ring's steep, cliff-like walls descend to broad internal terraces. The inner ring consists of a circular band of icy mountains creating a crown shape with a diameter of 140 kilometers (87-miles). This view looks toward the leading hemisphere of Tethys (1062 kilometers, or 660 miles across). North on Tethys is up and rotated 2 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on January 2, 2009. The view was obtained at a distance of approximately 816,000 kilometers (507,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 58 degrees. Image scale is 5 kilometers (3 miles) per pixel. Tethys is one of Saturn's moons.
