Crater Terminator on Rhea
The terminator between light and dark throws Rhea's cratered surface into stark relief while the southern hemisphere is scored by bright icy cliffs. North on Rhea is up and rotated 42 degrees to the right in this 2-tile mosaic. This view looks toward the leading hemisphere of Rhea (1528 kilometers, or 949 miles across). The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 2, 2009. The view was acquired at a distance of approximately 181,000 kilometers (112,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 91 degrees. Image scale is 1 kilometer (3,300 feet) per pixel.
