Domain Definition
Noah Webster [Noun] A carrying out or away; also, a lifting or extolling; exaltation.. Source: Webster's 1828 American Dictionary.
Aerospace A perturbation of the moon in its orbit due to the attraction of the sun. This results in an increase in the eccentricity of the moon's orbit when the sun passes the moon's line of apsides and a decrease when perpendicular to it. See lunar inequality. Evection amounts to 1 degree 15 minutes in the moon's longitude at maximum. (references)
Wikipedic Evection (Latin for carrying away), in astronomy, is the largest inequality produced by the action of the Sun in the monthly revolution of the Moon around the Earth. The deviation expressed by it has a maximum amount of about 10 15 in either direction. It may be considered as arising from a semi-annual variation in the eccentrivity of the Moon's orbit and the position of its perigee. Evection was discovered by Claudius Ptolemy. (references)
Wiktionary [Noun] (astronomy) Modification of the lunar orbit due to the gravitational effects of the Sun. (references)

Extended Definition: EVECTION

Evection

Evection (Latin for carrying away), in astronomy, is the largest inequality produced by the action of the Sun in the monthly revolution of the Moon around the Earth.

Evection causes the Moon's ecliptic longitude to vary by approximately 1.27 degrees, with a period of about 31.8 days. It arises from a periodic variation of the eccentricity of the Moon's orbit and the position of its perigee, caused by the action of the Sun. Evection was known in ancient times, and its discovery is usually attributed to Hipparchus.
