Moons of Other Planets


When you think of moons, you probably think of our own bright moon, but there are many other moons in our solar system. Moons orbit planets and are made of ice or rock. Most moons have no atmosphere. They are very hot or very cold. Some are dark. Some are even lumpy.

Moons were created 4.5 billion years ago when the rest of the solar system was made. Not all planets have moons. Mercury and Venus have no moons. Earth has only one. Mars has two. The large gas planets have more moons. Because these planets are so large, they have a huge magnetic field that can pull in moons.
