The moon is roughly 238,000 miles away from Earth. Earth orbits the sun. Earth is roughly 93 million miles from the Sun. The Sun is the center of our solar system. The Earth's Moon is located in orbit around the Earth. There are other moons in orbit around other planets. There are many moons in our solar system. If you're specifically referring to the one that orbits Earth, then... well, that's your answer. It orbits Earth.
The Earth's Moon is the fifth largest in the whole solar system, and is bigger than the planet Pluto. The Moon has a nearly circular orbit (e=0.05) which is tilted about 5 to the plane of the Earth's orbit. Its average distance from the Earth is 384,400 km. The combination of the Moon's size and its distance from the Earth causes the Moon to appear the same size in the sky as the Sun, which is one reason we can have total solar eclipses.
