The Moon is our nearest planetary neighbor, orbiting the Earth every 27 days. It’s held by Earth’s gravity, although it gets about an inch and a half farther away every year. When first formed, about 4.5 billion years ago, the Moon was about 10 times closer to Earth, affecting the planet’s spin so much that a day on Earth back then was only about 4 hours long. The Moon is Earth’s only natural satellite and the largest satellite in our solar system, relative to the size of its planet, and the fifth largest overall with a diameter of 2,159.2 miles (3,475 km) and is 6,783.5 miles (10,917 km) around at its equator; larger than Pluto. The Moon is the source of many legends, myths, science fiction, religions, and psychological affects, as well as the spectacular solar eclipses witnessed around the world.
