One of Saturn's strange co-orbital moons, Epimetheus (113 kilometers, 70 miles across) was captured by Cassini in this view. Irregularly shaped Epimetheus occasionally swaps orbits with nearby Janus (see PIA06603) and both moons play a role in maintaining the outer edge of Saturn's bright A ring.
The image was taken in visible light with the narrow angle camera on January 22, 2005, from a distance of approximately 2.5 million kilometers (1.6 million miles) from Epimetheus and at a Sun-Epimetheus-spacecraft, or phase, angle of 90 degrees. Resolution in the image is 15 kilometers (9 miles) per pixel. The image has been contrast-enhanced to aid visibility.
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.
