The Half Moon

The Half Moon, also known as the first or third quarter moon, occurs when the moon is half illuminated by the Sun as seen from Earth. This phase happens midway through the lunar cycle, approximately one week after a new moon. During the half moon, half of the moon’s visible side is lit up, creating a clear division between the illuminated and dark portions. It’s a natural and predictable part of the moon’s orbit, marking important stages in its cycle, and provides a striking visual that explains the moon’s changing appearances over time.
