Skathi

Skathi, also named Saturn XXVII and originally spelled Skadi, is a natural satellite of the planet Saturn. Skathi is one of Saturn's irregular moons, in its Norse group of satellites. It was discovered on September 23, 2000, by a team of astronomers led by Brett Gladman. The team announced their discovery on December 7, 2000, along with seven other satellites of Saturn, namely; Tarvos, Ijiraq, Thrymr, Siarnaq, Mundilfari, Erriapus, and Suttungr. The moon was named after Skaði, a figure in Norse mythology, as part of an effort to diversify the largely Greek and Roman names of astronomical objects.

Skathi takes just over 725 days to complete an orbit of Saturn and it is estimated to take 11.10±0.02 hours to rotate on its axis. It orbits at a greater distance from Saturn than many of the planet's other satellites, with a large orbital inclination and eccentricity, and it moves in a retrograde direction. Not much is known about Skathi, because it is a dim object. Other than Earth-based observations, it has only been observed by the Cassini probe, and even those measurements were taken at a distance of nearly 9.7 million kilometres (6 million miles).
