Earth's Satellite

The Moon is the Earth's only natural satellite (you might not be used to hearing the word "satellite" like this, but in fact its definition is: "A celestial body, or object in space, that orbits around a larger body"). Most astronomers believe that the Moon was formed about 4.51 billion years ago—about 30 million years after the Earth—as the result of a massive impact between the Earth and a planet-sized asteroid, known as Theia. The moon is about 3,474 km in diameter, which is just less than a quarter of Earth's 12,742 km diameter, and orbits at a distance from earth of 384,400 km.
