Moon Distances from Earth - 2021
According to Nasa the average distance between the Earth and the Moon is approximately 384,400 kilometers (238,855 miles), however this varies by around 50,000 km each month owing to the Moon's eleptical orbit.
This variation in distance matters for a number of reasons. When the moon is closest (preigee) it will appear both bigger and brighter. When this coincides with a full moon it is known as a "supremoon" and can appear up to 17% bigger and 30% brighter. The proximity of the moon also affects the size of the tides, with the tidal range being greatest when the moon is closest.
