Orbit of the Moon orbit of the Moon is distinctly elliptical, with an average eccentricity of 0.0549. The non-circular form of the lunar orbit causes variations in the Moon's angular speed and apparent size as it moves towards and away from an observer on Earth. The mean angular movement relative to an imaginary observer at the Earth-Moon barycentre is ° per day to the east (Julian day 2000). The Moon's elongation is its angular distance east of the Sun at any time. At new moon, it is zero and the Moon is said to be in conjunction. At full moon, the elongation is 180°
A Trip to the Moon and established it definitively as a landmark in the history of cinema. LeRoy's incomplete print became the most commonly seen version of the film and the source print for most other copies, including the Cinémathèque française's print. A complete version of the film, including the entire celebration sequence, was finally reconstructed in 1997 from various sources by the Cinémathèque Méliès, a foundation set up by the Méliès family.
