Atlas is a moon of Saturn.

Atlas was discovered by Richard Terrile in 1980 (some time before November 12) from Voyager photos and was designated S/1980 S 28. In 1983 it was officially named after Atlas of Greek myth, because it "holds the rings on its shoulders" like the Titan Atlas held the sky up above the Earth. It is also designated as Saturn XV.

Atlas seems to be a shepherd satellite of the A ring. Furthermore, in 2004 a faint, thin ring, temporarily designated R/2004 S 1, was discovered within Atlas's orbit.

High-resolution images taken in June 2005 by Cassini reveal a saucer-shaped moon with a large equatorial ridge.

Atlas is significantly perturbed by Prometheus and to a lesser degree by Pandora, leading to excursions in longitude of up to 600 km (~0.25°) away from the precessing keplerian orbit with a rough period of about 3 years. Since the orbits of Prometheus and Pandora are chaotic, it is suspected that Atlas's may be as well [1].
