What are the phases of the moon?
user
The moon undergoes different phases as it orbits around the Earth. These phases include the New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent. The moon's phases are a result of its position between the Earth and the Sun. As it orbits the Earth, different portions of the moon become illuminated by the Sun, leading to different phases. 

During a New Moon, the side of the moon facing Earth is not lit, appearing completely dark. As the moon moves in its orbit, a small sliver of the illuminated portion becomes visible, marking the Waxing Crescent phase. The illumination gradually increases until the First Quarter, when half of the moon is visible. The moon continues to wax until it reaches the Full Moon phase, where the entire face of the moon appears illuminated. Following the Full Moon, the moon wanes, with the illuminated portion gradually decreasing until it reaches the Third Quarter, marking half of the moon's face being visible. The illuminated portion continues to decrease, leading to the Waning Crescent phase, before transitioning back to the New Moon. These phases repeat in a continuous cycle, taking approximately 29.5 days to complete.
