Cassini spies two of the small, irregular moons that patrol the outer edges of Saturn’s main rings. Prometheus (86 kilometers, 53 miles across) hugs the interior of the F ring right of center, while Janus (179 kilometers, 111 miles across) hangs in the foreground below center. Hints of craters can be seen on Janus. This view looks toward the unilluminated side of the rings from less than a degree above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 14, 2007 at a distance of approximately 1.6 million kilometers (1 million miles) from Saturn. Image scale is about 10 kilometers (6 miles) per pixel.
