Penelope Crater

April 4, 2006

This dramatic close-up of Tethys shows the large crater Penelope lying near center, overprinted by many smaller, younger impact sites.

Three smaller impact features of roughly similar size make a line left of Penelope that runs north-south: (from bottom) Ajax, Polyphemus and Phemius.

Features on Tethys are named for characters and places from "The Iliad" and "The Odyssey." The largest impact structure on Tethys is named Odysseus.

The view is toward the Saturn-facing hemisphere on Tethys (1,071 kilometers, or 665 miles across). North is up.

The image was taken in polarized ultraviolet light with the Cassini spacecraft narrow-angle camera on Feb. 25, 2006 at a distance of approximately 165,000 kilometers (103,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 23 degrees. Image scale is 984 meters (3,227 feet) per pixel.
