The Moon

Either an image of light in the dark, or one that triggers a werewolf induced fear, the Moon has been in our skies for around 4.5 billion years. It is the Earth’s only permanent natural satellite and is thought to have formed from a giant impact between left over debris from Earth and a Mars sized body called Theia. The moon causes the Earth to have much larger tides and 24-hour days, without they Moon they would only be 6-8 hours.
