  Cassini provides a window on the awesome scale of the Saturn system, with the giant planet dominating one of its smaller satellites.

Orbiting here, just outside the main ring system, is Janus (179 kilometers, 111 miles across).

This view looks toward the unilluminated side of the rings from about 16 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 13, 2008. The view was obtained at a distance of approximately 1.6 million kilometers (1 million miles) from Janus and 1.8 million kilometers (1.1 million miles) from Saturn. Image scale is 10 kilometers (6 miles) per pixel on Janus.

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.
