Interestingly and not coincidentally, the words "moon" and "month" come from the same root. The lunar cycle takes 29.53 days - nearly a month - to complete, allowing us to see it changing and morphing from new moon to new moon. The percentage of illumination also varies during each phase, ranging from zero percent during the new phase to 100 percent during the full phase. The Moon completes an orbit - or revolution - around the Earth in 27.32 days, similar to how the Earth goes around the Sun in 365 days.Īs a result, the Moon sometimes finds itself hidden, partially hidden, partially lit, or fully lit up by the Sun, depending on whether it is blocked or not by the planet we live on. So, why does the Moon change shape throughout the month? The Sun is actually the only source of light in the solar system. Why? Because The Moon doesn't produce or emit its own light. The Moon simply reflects the light of the Sun, and its bright part experiences daytime, just like any other planet in the Solar System. There are several myths and misconceptions about the Moon, its apparent brightness, and its phases.įor instance, the concept of moonlight is nothing but sunlight reflecting off the Moon's surface. The lunar cycle is the result of the interaction between the Sun, the Moon, and the Earth. ![]()
