The Moon is a spherical rocky body, like the Earth but significantly smaller. Throughout the month the Moon changes shape, from new Moon, through the crescent phase, to a half Moon, and then full Moon, before disappearing again back to New Moon. The Moon emits no light of its own, this effect is purely down to how we see the change in illumination from the Sun as the Moon slowly orbits the Earth.
