Why does the moon goes through phases?
The moon goes through phases because it orbits Earth about once a month, or about every 28 days. As we look up at the moon, we are watching it slowly move east through the sky. As it gets farther from the sun, it appears to get bigger – what we call “waxes”. After the full moon, the moon continues it’s journey around Earth and appears to move back toward the sun. As it does, it gets smaller – or “wanes”.
