Definition of apolune in English:

apolune

nounˈapə(ʊ)luːnˈapəˌlo͞on

mass noun

The point at which a spacecraft in lunar orbit is furthest from the moon.
The opposite of perilune
Example sentencesExamples
- The spacecraft consists of an orbiter which goes around the Moon at about 100 km altitude near a polar orbit, and a relay satellite on an elliptical orbit with initial apolune at 2,400 km.
- The perilune slowly decreased to about 300 km and the apolune increased to about 3000 km, while the argument of perilune drifted around the south pole.
- This paper investigates the least maneuver velocity through the tolerable apolune and other lunar orbit elements.
- However, to be useful, the apolune must be located at one of the orbital nodes.
- Having an apolune closer to the Moon would increase the efficiency for lunar mapping at higher resolutions than carried out by the Clementine and Lunar Prospector probes.

Origin

1960s: from apo- + Latin luna 'moon', on the pattern of apogee.
