Since the moon's orbit is elliptical (oval-shaped), its distance varies from about 221,463 miles (356,334 kilometers) at perigee (closest approach to Earth) to 251,968 miles (405,503 kilometers) at apogee (farthest point). The average distance from the moon to the Earth is 238,857 miles (384,392 kilometers).
How do we know how far away the moon is? The exact distance between the Moon and Earth varies since the Moon follows an elliptical (oval) orbit, but on average the Moon is 384,399 km away. If you had a piece of string that long, you could wrap it all the way around the Earthâs equator almost ten times.
