Moon gazing on a windy night
Did you know that the same side of the moon alway faces toward the Earth. This is because it has a synchronous rotation. This means that the Moon is locked in phase with its orbit so that the same side is always facing toward the Earth.
A few degrees of the far side can be seen from time to time. This is because the Moon does not orbit the Earth in a completely circular orbit, making it appear to 'wobble'.
