![]() Also, closest ( perigee) and farthest (apogee) distances are given. ![]() Here in this article, we will know about the mean or average distance of the moon from earth. The closest distance is called perigee, whereas the farthest distance between the moon and earth is known as apogee. At some point, the moon is closest to earth and at some point in the orbital path, the moon would be the farthest from the earth. So, there is always variation between the earth and moon’s actual distance. Also, according to Lunar Laser Ranging (LLR) experiment, scientists have concluded that the moon is drifting away around 3.8 cm in one year from the earth. Because our moon does not orbit Earth in a perfect circle but the path is a little elliptical. In actuality, the distance between the moon and earth always changes.
