National Geographic: The Story of Earth - Movie

Dive into the Giant Impact Hypothesis, the leading scientific theory explaining how the Earth's Moon was born. This theory suggests that billions of years ago, a catastrophic, Mars-sized planetary body, named Theia, slammed into the early Earth, resulting in a massive collision. The resulting debris from this cosmic crash eventually coalesced to form our solitary satellite—the Moon. It's our cosmic sibling, forged in chaos!

The giant-impact model suggests that at some point in Earth's very early history, these two bodies collided. During this massive collision, nearly all of Earth and Theia melted and reformed as one body, with a small part of the new mass spinning off to become the Moon as we know it. | Science Queries 360
