Saturn Rings II

Across the expanse of Saturn's rings, the Cassini spacecraft spies two small moons in consort.

Atlas (32 kilometers, or 20 miles across) is seen exterior to the bright outer edge of the A ring. Daphnis (7 kilometers, or 4.3 miles across), below Atlas in this view, orbits Saturn within the narrow Keeler Gap. The presence of Daphnis is revealed by the waves it raises in the ring material surrounding it on the edges of the gap. Daphnis and its waves moved between exposures taken to create this color view, resulting in their slight displacement in each color.
