Atlas and the "Roche Division"

Caption NASA:"Atlas, seen here, is one of the two moons that ply the Roche Division -- the region between Saturn's A and F-Rings. Prometheus also orbits within this Division.
This view looks toward flying-saucer-shaped Atlas (32 Km, or about 20 miles across at its widest point) and the unilluminated side of the Rings from about 37° above the Ring-Plane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 9, 2008. The view was obtained at a distance of approx. 1,5 MKM (such as about 925.000 miles) from Atlas and at a Sun-Atlas-Spacecraft angle of 44°.
Image scale is roughly 9 Km (approx. 6 miles) per pixel".
