PHASES OF MOON


Understanding The Moon Phases

Have you ever wondered what causes the moon phases? We all know that its appearance changes over time. But why? The good way to understand the phases of the moon is to examine an earth-moon-sun diagram:

PHASES OF THE MOON
The revolution of the Moon around the Earth causes the Moon to appear to change shape in the sky. These different shapes are called "phases" of the moon. The Moon passes through a cycle of eight phases every 29.5 days. There is no definite starting point for the cycle, but phases follow one behind the other in a strict order. You will find images of each of the eight phases, as well as a breif description of each phase. The images reflect the order the phases are viewed from the earth.
