- A new collision hypothesis would have required the Earth to collide with another planet-sized object at the end of its extinctions .
- This created a large amount of debris in Earth orbit that coalesced to form the Moon.
- Scientists have proposed many ideas about the formation of the Moon.
- The leading contender, the giant impact hypothesis, speculates that when Earth was a young planet just beginning to form, it was hit by another nearby emerging planet called Theia.
- The Giant Impact Hypothesis is one of the theories about the formation of the Moon.
- In this theory, a Mars-sized object collided with the Earth at an angle about 4.5 billion years ago, ejecting a large amount of material and forming a disk around the Earth. Out of this disk emerged a giant moon.
