It may be hard to spot it, but the tiny white dot in the lower right part of the photo is Mimas, one of Saturn’s moons. Discovered by William Herschel in 1789, Mimas is named after the son of Gaia in Greek mythology. The Cassini Orbiter took this picture using its wide angle camera at a distance of over a million miles. And the bright speck that is Mimas just happened to be perfectly positioned against the shadow of Saturn’s rings. This view looks toward the sunlit side of the rings from about 10 degrees above the ringplane.
