This NASA handout image released 26 October 2006 shows a portrait of Janus against the cloud-streaked backdrop of Saturn. Like many small bodies in the solar system, Janus (181 kilometers, or 113 miles across) is potato-shaped with many craters, and the moon has a surface that looks as though it has been smoothed by some process. Like Pandora (see PIA07632) and Telesto (see PIA07696), Janus may be covered with a mantle of fine dust-sized, icy material. The image was taken using a spectral filter sensitive to wavelengths of infrared light centered at 930 nanometers. The view was acquired with the Cassini spacecraft narrow-angle camera on 25 September 2006, at a distance of approximately 145,000 kilometers (90,000 miles) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 62 degrees. North on Saturn is up. Image scale is 871 meters (2,858 feet) per pixel. AFP PHOTO/NASA/JPL/SPACE SCIENCE INSTITUTE/HO =GETTY OUT=..(Photo credit should read HO/AFP/Getty Images)
