Epimetheus, seen here by NASA's Cassini spacecraft, with Saturn in the background, is lumpy and misshapen, thanks in part to its size and formation process. Bombardment over the eons has left this tiny moon's surface heavily pitted.
NASA's Cassini spacecraft captured this view of Saturn's moon Epimetheus (116 kilometers, or 72 miles across) during a moderately close flyby on Dec. 6, 2015. This is one of Cassini's highest resolution views of the small moon.
Although Epimetheus appears to be lurking above the rings here, it's actually just an illusion resulting from the viewing angle of NASA's Cassini spacecraft. In reality, Epimetheus and the rings both orbit in Saturn's equatorial plane.
Saturn's moon Epimetheus casts a shadow across colorful rings in this image taken by NASA's Cassini spacecraft before the planet's August 2009 equinox. Epimetheus is visible as a small dot at the center of the bottom of the image.
