Hyperion Information Page

Hyperion is the largest of Saturn's irregular, nonspherical moons. Hyperion's mean radius is 135 km and has dimensions 410 x 260 x 220 km. Hyperion's density is slightly more than half that of water, indicative of a highly porous, water-ice composition. Hyperion rotates chaotically, tumbling unpredictably through space as it orbits Saturn. Hyperion orbits at a mean distance of 1,500,000 km from Saturn in an eccentric orbit.
