Hyperion is an irregularly shaped moon of Saturn, discovered in 1848 almost simultaneously by William Cranch Bond and his son George Phillips Bond at Harvard College Observatory and by William Lassell in England. It is notable for its sponge-like appearance, with deep craters and a very low density suggesting that it is porous and made largely of water ice. Hyperion also has a chaotic rotation, tumbling unpredictably because of gravitational interaction with the much larger moon Titan. It was named for a Titan in Greek mythology, and the Cassini spacecraft sent back close images during flybys in the 2000s.
