<P> Lunar distance ( LD or Δ ⊕ L ( \ textstyle \ Delta _ ( \ oplus L ) ) ) , also called Earth -- Moon distance , Earth -- Moon characteristic distance , or distance to the Moon , is a unit of measure in astronomy . It is the average distance from the center of Earth to the center of the Moon . More technically , it is the mean semi-major axis of the geocentric lunar orbit . It may also refer to the time - averaged distance between the centers of the Earth and the Moon , or less commonly , the instantaneous Earth -- Moon distance . The lunar distance is approximately a quarter of a million miles ( 7008400000000000000 ♠ 400 000 km ) . </P>
