Caliban
Caliban is a small, irregularly-shaped moon of Uranus.
Facts About Caliban:
- Caliban's orbit is retrograde, meaning that it orbits its parent planet (Uranus) in the opposite direction to the planet's rotation.
- Caliban is, on average, the 20th moon from Uranus. Elliptical orbits mean that not all moons are always in the same order from the main planet.
- It is likely that Caliban is a captured moon; that is, it did not form alongside Uranus but was captured into its current position some time after Uranus formed.
