Saturn's moons Janus and Prometheus look close enough to touch in this stunningly detailed view.
From just beneath the ringplane, Cassini stares at Janus (179 kilometers, 111 miles across) on the near side of the rings and Prometheus (86 kilometers, 53 miles across) on the far side. The image shows that Prometheus is more elongate than Janus.
The view takes in the Cassini Division (4,800 kilometers, or 2,980 miles wide), from its outer edge to about halfway across its width.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 29, 2006 at a distance of approximately 218,000 kilometers (135,000 miles) from Janus and 379,000 kilometers (236,000 miles) from Prometheus. Image scale is about 1 kilometer (0.6 mile) per pixel on Janus and 2 kilometers (1 miles) per pixel on Prometheus.
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.
