Hyperion

Hyperion is a natural satellite of Saturn discovered by William Herschel in 1789. It is distinguished by its irregular shape, chaotic rotation, and extensive cratering, making it one of the most unusual moons in the Solar System. Hyperion's low density indicates that it is composed largely of water ice with a porous structure. Its chaotic rotation, unique among regular solar system bodies, is due to the gravitational influence of Saturn's larger moon, Titan. The moon is named after Hyperion, a Titan from Greek mythology, and is also known as Saturn VII. In Hebrew, Hyperion is called היפריון (Hipriyon). In Latin, it is Hyperio, and in Japanese, it is ハイペリオン (Haipersion). Hyperion's surface features include numerous impact craters, with the largest being approximately 120 kilometers in diameter and 10 kilometers deep, and it has a highly reflective surface due to its water ice composition.
