Moon Phases 🌙

The Moon orbits around Earth while Earth orbits around the Sun, resulting in a constantly changing angle between the three celestial bodies. The reflection of the sunlight when it falls on the Moon’s surface is the leading cause of the phases of the Moon ✨

We see the Moon’s disk change from all dark to all light to all dark again. This period is called a lunar cycle. The cycle length can vary, but on average, it is 29.5 days 🗓

Astronomers broke down this cycle into four primary Moon phases: New Moon, First Quarter, Full Moon, and Last Quarter. And four secondary phases: Waxing Crescent, Waxing Gibbous, Waning Gibbous, and Waning Crescent 🔭

The “Moon age” is the value that measures the days that have passed since the last new Moon. As mentioned before, this period is, on average, 29.5 days 🕙
