The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. This is caused by the different angles from which we see the bright part of the Moon's surface. These are called 'phases' of the Moon.
The Moon passes through four major shapes during a cycle that repeats itself every 29.5 days. The moon phases always follow one another in the same order. What you see when you look at the moon depends on its location in relationship to the sun and Earth.
