The moon is Earth’s closest neighbor. It is the brightest object in the night sky. Scientists have studied the moon for thousands of years. Learn more about the moon.

The moon is about 4½ billion years old. It is made of rock. It is covered with craters. They were made when objects hit the moon’s surface.

The moon has no weather. That means there is no wind or rain. Footprints left by astronauts could last billions of years.

The moon has eight phases. Once a month, we see a full moon. Sometimes we can’t see the moon at all. The shape we see depends on how the Earth, sun, and moon line up.
