Moon Formation

4.44 Billion Years Ago
About 60 million years after Earth forms.
In a cataclysmic event, a Mars-sized object named Theia collided with the early Earth, sending massive amounts of debris into orbit. This debris coalesced over time to form the Moon, which eventually became tidally locked to the Earth, stabilizing the planet’s axis and paving the way for the development of life. The Moon is comprised of lighter elements because the heavier elements of Earth had already sunk to the center.
