How do the moon phases that we can see from the Earth originate? View from the Earth Earth's orbit around Sun, slope of the Moon's orbit relative to the ecliptic and orbit around barycenter are neglected.

Position of the Moon: The course of a saros (approx 18 years): Using mouse you can move in space and rotate the scene. The animation is speeded up. (c) Václav Černík 2017–2025. This app is based on diploma thesis (Charles University, Faculty of Science).

A quoi sont dues les phases de la Lune que nous pouvons observer depuis la Terre? La vue de la Lune depuis la Terre L´orbite terrestre autour du Soleil, l´inclinaison de l´orbite lunaire par rapport à l´ecliptique et l´orbite du barycentre sont négligées.

The influence of the Sun and the slope of the Moon's orbit towards ecliptic are neglected. Highlighted deformation is illustrative. Distances and dimensions are not in scale.
