Cordi's Phases Of The Moon Quiz

Everything you need to know for the test!
The phases of the Moon is how much of the Moon we can see that is reflecting off the Suns light, or being lit up by the Sun as it orbits around Earth. When something is forever circling a planet, caught in their gravitational field, it is called being in orbit. The Moon has been in orbit of the Earth for millions if not billions of years, and probably a long long time to come. As the Moon orbits around us, we can only see a certain amount of it because the Sun’s Read morerays only come from one direction, and therefore never being able to light up the entire moon, only half of it. The part of the Moon facing the sun is lit up. The part facing away from the sun is in darkness. This means that the Moons appearance varies every night, which we have divided up into 8 main phases called the phases of the Moon. The phases of the Moon are similar to the phases of Venus, the only difference being in the phases of Venus we are on the outside looking in and in the Phases of the Moon we are on the inside looking out. A Moon cycle lasts approximately 29.5 days, and half the moon is always being lit up by the Sun, the main source of light in our solar system.
