  Rhea's distinctive bright and relatively fresh rayed crater lies in stark contrast to the large round basin which sits along the terminator in this unmagnified view.

Rhea (1,528 kilometers, 949 miles across) is Saturn's second-largest moon.

North on Rhea is up and rotated about 15 degrees to the left. The sunlit terrain shown here is on the moon's leading hemisphere.

The image was taken in visible light with the narrow angle camera on August 31, 2005, from a distance of approximately 1.6 million kilometers (1 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 52 degrees. The image scale is 10 kilometers (6 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
