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).
A lunar distance (LD) is an astronomical measurement of the distance from the Earth to the Moon. The average distance from Earth to the Moon is 384,403 kilometers or 238,857 miles, but the actual distance varies over the course of the orbit of the moon. Depending on the Moon's location in its orbit, it is between 225,623 and 252,088 miles away from Earth. This is about 30 times the diameter of the Earth.
