The Phoebe Ring is a ring of Saturn. It is named after the moon Phoebe, and it is fed by dust from Phoebe’s surface.
In October of 2009, the Phoebe Ring was discovered as a ring of dust around Saturn. It is just inside the orbit of Phoebe, the largest outer moon of Saturn. The disk was aligned at the time of discovery directly to Earth’s orbit. If you could see the Phoebe Ring from Earth, it would be the size of two full Moons. The Phoebe Ring goes from 128 to 207 times Saturn’s radius. Some calculations say that it may go to 300 times Saturn’s radius and to around the orbit of Iapetus, at 59 times Saturn’s radius.
