Daphnis is seen as a tiny disk in the Keeler Gap of Saturn's rings in this image taken by the Cassini spacecraft on May 1, 2005, from a distance of 525,000 km (326,000 miles). Image: NASA/JPL.

Daphnis is a small inner moon of Saturn, which orbits within the Keeler Gap of the A-ring of Saturn's rings. The Keeler Gap edges are similar to the scalloped edges of the 322-kilometer-wide (200-mile) Encke Gap, where Pan resides. Daphnis is also known as Saturn XXXV and was given the provisional name S/2005 S1 following its discovery.
