As a consequence the altitude ofthe Moon above the horizon, as seenform a certain location, is at maximum 5°lower or higher than the altitude of theSun.Fig. A completerevolution of the Moon around the Earth(sidereal month) takes 27.3 days.The orbit of the Moon is tilted at an angleof about 5° with respect to the ecliptic (theplane of the orbit of the Earth around theSun).

Codermatz' - TriesteInformation and contacts: - IntroductionThe Moon is, after the Sun, the brightestcelestial object in the sky and the easiestto observe.The Moon behaves in a little strange way:some days it is visible during the night,others during the day, some times it is fulland others only partially illuminated.This use case helps us, using Stellarium,to understand the orbit of the Moon andthe main phenomena related to it.2 The orbit of the MoonThe Moon moves around the Earth on aelliptical orbit: the semi-major axismeasures 384000 km.
