Rhea's Battered Surface
November 17, 2004
This view of Saturn's second-largest moon, Rhea (1,528 kilometers, or 949 miles, across), shows some of the large craters that cover its surface. There is a bright feature near the moon's right limb, possibly a large, rayed crater or bright icy material exposed by internal processes. The image was taken in visible light with the Cassini spacecraft narrow angle camera on Sept. 26, 2004, at a distance of 7.1 million kilometers (4.4 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 75 degrees. The image scale is 43 kilometers (27 miles) per pixel. The image has been magnified by a factor of four and contrast-enhanced to aid visibility.
