The satellite of the earth is the Moon. A satellite is an object that orbits around a larger object, and in this case, the Moon orbits around the Earth. The Moon is our closest neighbor in space, and it takes about 27.3 days to orbit around the Earth. The Moon is also the fifth-largest moon in the solar system and the largest relative to its host planet. It plays an important role in our daily lives, causing tides in the ocean and influencing our planet's rotation.
