Moon Phases 3 min History Channel - Phases 4 min – music only Moonlight Sonata by Beethoven As the moon orbits (revolves) the Earth, we SEE different parts of the half lit moon. The different shapes (parts) are called the moon’s phases. Waxing – lit portion of the moon that seems to be getting larger Waning – lit portion of the moon that seems to be getting smaller

Moon Phases Because Earth rotates,
your part of the Earth faces the moon once a day. No matter where you are on Earth, the moon phase will look the same. 2 ½ min A Year in the Life of the Moon 3 min Time Lapse explains Libration

The entire lit side is facing away from Earth. Beginning of the Lunar Cycle

First Quarter Half of the bright side is visible
The moon has completed one-quarter of a full revolution around the Earth. LIGHT is on the RIGHT.

Waxing Gibbous Bulging More than half is lit LIGHT is on the RIGHT.
13
Full Moon Completely lit up
Moon is halfway through its orbit around the Earth. ALL of its lit side is facing the Earth.
