Lunar Cycle

The video tutorial explains the lunar cycle, which is the 29.5-day period during which the moon goes through eight phases. These phases are determined by the moon's orbit around the Earth and its position relative to the sun. The phases include new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. The video describes how the moon appears to change shape due to the amount of sunlight it reflects. The tutorial also covers the concepts of waxing (growing) and waning (shrinking) as the moon transitions between phases.
