<span class="Apple-style-span" style="font-size: large;">The revolution of the Moon around the Earth makes the Moon seem to change its shape in the night sky. Actually it does not. This is caused by the different angles we see from the bright part of the Moon's surface. The Moon goes through 4 major shapes during a cycle that repeat itself every 28 days.</span><br />
