• Epimetheus, A Moon of Saturn

This image of Epimetheus was acquired by the Voyager 1 spacecraft on November 11, 1980. Epimetheus is the fifth satellite of Saturn. It was discovered by R. Walker in 1980. Epimetheus was the son of Iapetus and brother to Prometheus and Atlas. Epimetheus means hindsight in Greek. It has an irregular shape with a size of 144x108x98 kilometers (89x67x61 miles) in diameter. It is traversed by several large and small grooves, valleys and ridges. Several craters larger than 30 km can be seen on its surface. The pervasive cratering indicates that its surface must be several billion years old. In this image, Saturn's F Ring casts a shadow across Epimetheus' surface.
