What is Earth-Moon distance?

The Earth-Moon distance (or lunar distance) is the distance from the Earth to the Moon. The average Earth-Moon distance is equal to approximately 384.403x106 meters (Earth-Moon distance ≈ 384.403x106 m), the base unit of length in the International System of Units (SI). It is also equal to about 384,403 kilometers (km) (an SI unit of length), or approximately 238,857 miles (mi) or 1.2611647x109 feet (ft), which are US customary / Imperial units of length.

The Earth-Moon distance varies during the course of the orbit of the Moon as the Moon follows an elliptical path around the Earth. Thus, at the perigee (the closest point of the Moon's orbit) the distance from the Earth to the Moon is 363,300 km or 225,700 miles and at the apogee (the most distant point of the Moon's orbit) the distance from the Earth to the Moon is 405,500 km or 252,000 miles.

The Earth-Moon distance is used in astronomy. Common astronomical measurement units include the parsec (Earth-Moon distance ≈ 1.2457x10-8 pc) and the light-year (Earth-Moon distance = 4.0632x10-8 ly).

Plural:
