Moon

From TARDIS Index File, the free Doctor Who reference.

This article is about moons in general. For Earth's moon, see the Moon.

A moon (also known as a natural satellite) is an astronomical object that is found in orbit around a planet. Some moons, like Voga, are planetoids brought into orbit around a planet by the planet's gravity, while others are the result of a collision between objects during the formation of a solar system.
