Solve this instance: 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.
