This movie highlights the dynamic of the Earth - Moon system. You can use it to illustrate the moon phases (~28 days) and its synchronous orbit.
Note that the side of the Moon facing the Earth is always the same one. We say that its orbit is synchronous.
Note that everything is not to scale in this animation. See the animation “Eclipses” to observe those phenomena.
Click on to stop the movie and show the Moon the way we see it from the Earth.
