Full Answer

The gibbous moon phase occurs twice in each complete lunar cycle. As the moon transitions from a new moon to a full moon, the moon undergoes a waxing gibbous phase prior to becoming a full moon. As the cycle reverses, the moon becomes a waning gibbous moon as it transitions from a full moon to a third quarter moon.

    How much of the moon is always lit by the sun?

    A:

    Half of the moon is always lit by the sun, unless the sun is eclipsed by the Earth. The portion of the illuminated moon viewed from Earth depends on the moon's orbit. As the moon orbits, different portions of shadow and illumination are seen from Earth, creating the moon's phases.
