Atlas (at'-las) is a moon of Saturn. Atlas was discovered by Richard Terrile in 1980 from Voyager photos and was designated 1980 S 28. In 1983 it was officially named after Atlas of Greek mythology, 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 in Atlas' orbit.
