Lunar Cycle Definition
The lunar cycle is the continuous sequence of phases the Moon passes through as it orbits Earth, taking about 29.5 days to complete one full cycle.
Phases of the Lunar Cycle
The main phases are new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. Each phase reflects a different portion of the Moon’s sunlit side visible from Earth.
Why the Lunar Cycle Matters
The lunar cycle influences tides, cultural calendars, and traditional timekeeping. It also helps explain predictable changes in moonlight and visibility throughout the month. Learn more about lunar phases from NASA.
