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).
The Moon is at an average distance of 238,855 miles (384,400 kilometers) away from Earth. That is about the width of 30 Earths. Because the Moon does not orbit Earth in a perfect circle, but instead travels in a slightly elliptical orbit, its distance from Earth varies between 225,700 miles (363,300 kilometers) and 252,000 miles (405,500 kilometers).
