  Janus, passing between the rings and Cassini, poses for a snapshot by the spacecraft's narrow-angle camera.

Janus (179 kilometers, 111 miles across) is closer to Cassini than the rings are here. This view looks toward the northern, sunlit side of the rings from just above the ringplane. Janus has been brightened by a factor of 1.5 relative to the rings.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 28, 2009. The view was acquired at a distance of approximately 2.3 million kilometers (1.4 million miles) from Janus. Image scale is 14 kilometers (9 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. 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.
