|There is more information available on this subject at Natural satellite on the English Wikipedia.|
A natural satellite, more commonly referred to as a moon, is a celestial body that orbits a planet or smaller body, which is called the primary.
The large gas giants of Sol have extensive systems of moons, including half a dozen comparable in size to Earth's moon: the four Galilean moons, Saturn's Titan, and Neptune's Triton. Saturn has an additional six mid-sized moons massive enough to have achieved hydrostatic equilibrium, and Uranus has five. Jupiter has more than sixty moons, of which only four are colonized. Those moons are called Jovian Moons. Of the inner planets, Mercury and Venus have no moons at all; Earth has one large moon, Luna, and Mars has two tiny moons, Phobos and Deimos.
