Originally Answered: Why is the Moon drifting away by 1 cm each year? Because of tidal forces between moon and Earth. As Earth and moon pull each other, bulges are created on the surface.
A week after this, the Moon is 180Â° away from the Sun, so that Sun, Earth and Moon form a line. The Moon is fully illuminated by the Sun, so this is called Full Moon. The Earth's shadow points towards the Moon at this time, but usually the Moon passes above or below the shadow and no eclipse occurs. A week later the Moon has moved another quarter of the way around the Earth, to the Third Quarter position.
