Where did the Moon come from? The short answer is that we don’t really know. However, science is able to hazard a few educated guesses. There are five main theories about the origin of the Moon. The Fission Theory argues that the Moon used to be a part of our planet that was separated at some very early point of Earth’s history.
This would make the Moon part to what is currently the Pacific Ocean basin. The Capture Theory says that the Moon was just wandering the universe until our gravitational field caught it.
Other theories say our satellite was either condensed from a bunch of asteroids or the remains of Earth’s collision with an unknown Mars-sized planet.
Currently, the most likely candidate for the Moon’s origin story is the Ejected Ring Theory, which is better known as Giant Impact Theory.
According to this version, a protoplanet (a planet that is forming) called Theia collided with Earth. The ensuing cloud of debris eventually condensed into the Moon.
