When talking about Saturn satellites, some names come to mind. One of them is Titan, of course, the largest of all (its diameter is larger than Mercury). Enceladus is not without interest either, for its geysers of water vapor rich in potassium chloride, the curious Iapetus, a satellite of two-colored (one of its hemispheres is black as coal and the other is white as snow). More discreet, Phoebe also deserves our attention.
Phoebe is a member of the large family of icy bodies that orbit around the sixth planet of the Solar System. Its retrograde orbit and high density make it special. This 220-kilometer-diameter moon is 13 million kilometers from Saturn. It was discovered in 1898 by the American astronomer William Pickering. Is composed mainly of coal and frozen water.
Phoebe has a rough, circular shape, and reflects about 6% of sunlight. It is also quite red. Phoebe rotates on her own axis almost once every nine hours. That is, contrary to the other Saturnian satellites (except Hyperion), does not always show the same face to the planet.
