Moons

Bodies that orbit planets, ranging from the tiny to the gigantic. At least in Earth's solar system, moons are a common phenomenon - of the eight major planets, only Mercury and Venus are moonless.

The second largest moon in the Solar System (after Ganymede) is Titan, seen here with its parent planet Saturn. Its thick orange clouds cover a body that has almost twice the mass of Earth's Moon.
