Earth’s Mantle Holds Clues to Moon-Forming Collision

The Moon formed when a Mars-sized object called Theia collided with the proto-Earth (Gaia) around 4.5 billion years ago. The collision had a significant impact on the Earth, mixing the material of the two bodies and creating the Large Low-Velocity Provinces (LLVPs) in the mantle. This new simulation suggests that the mixing was more extensive than previously thought, and that the Theian material in the lower mantle could be responsible for the formation of the LLVPs. This research has implications for not only Earth, but also for how other rocky planets form.
