What are Lunar Phases?
Lunar phases are different stages in the cycle of the moon’s orbit around the Earth. As the moon moves, people on Earth see varying levels of its illuminated surface, from a new moon, in which the moon can’t be seen at all, to a full moon, in which people see the entire portion of the moon illuminated by the Sun. This cycle takes a little less than 30 days to complete, and it may be known collectively as the lunar cycle.
