Introduction to Lunar Phases The moon is a fascinating astronomical body that has fascinated humans for centuries. One of the most intriguing aspects of the moon is its various phases, which are the different ways in which the moon appears to us on Earth. These phases are caused by the changing angles between the sun, Earth, and moon. There are eight lunar phases, which are: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. The new moon occurs when the moon is between the sun and Earth, and we cannot see any of the moon's illuminated side. The waxing crescent phase is when we can only see a small sliver of the illuminated side. The first quarter phase occurs when half of the moon's illuminated side is visible. The waxing gibbous phase is when most of the illuminated side is visible, but the moon is not yet full. The full moon is perhaps the most well-known lunar phase, when we can see the entire illuminated side. The waning gibbous phase is when most of the illuminated side is visible, but the moon is beginning to shrink. The third quarter phase is when half of the moon's illuminated side is visible, but the opposite side from the first quarter. Finally, the waning crescent phase is when we can only see a small sliver of the illuminated side, and the moon is beginning to disappear from view.
