  Small, multi-faceted Epimetheus (113 kilometers, 70 miles across) wanders into Cassini's field of view, while Saturn's dark shadow cuts across the ringplane. Only a sliver of the outer A ring is seen here, including the narrow Keeler gap.

For a much closer view of crater-pocked Epimetheus see PIA06226.

This view is from 10 degrees out of the ring plane, gazing toward the lit face of the rings.

The image was taken in visible light with the narrow angle camera on Aug. 31, 2005 from a distance of approximately 2.1 million kilometers (1.3 million miles) from Epimetheus and at a Sun-Epimetheus-spacecraft, or phase, angle of 60 degrees. Resolution in the original image was 13 kilometers (8 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.
