384,400 KM. The average distance between Earth and the Moon is 384,400 kilometers (238,855 miles). This is about 30 times the diameter of Earth. The Moon’s orbit around Earth is elliptical, so the distance between the two bodies varies slightly. The semi-major axis has a value of 384,399 km (238,854 mi). The time-averaged distance between the centers of Earth and the Moon is 385,000.6 km (239,228.3 mi). The actual distance varies over the course of the orbit of the Moon, from 356,500 km (221,500 mi) at the perigee to 406,700 km (252,700 mi) at apogee, resulting in a differential range of 50,200 km (31,200 mi).
