Phoebe (moon)
Phoebe is a moon which goes around (orbits) the planet called Saturn. It takes eighteen months for Phoebe to go all the way around Saturn. It is half made out of rock, and half made out of ice. The ground on Phoebe is black, which means that it is very dark when seen from Earth. Phoebe does not have any air, and there is no water on its surface.
