Today, the most widely—accepted theory on the Moon's origin is the Giant Impact hypothesis, which holds that the Moon was formed from material hurled into space by this spectacular collision. The object thought to have hit the Earth was a Mars —sized body known as Theia, named after the mother of the Moon goddess in Greek mythology.
The Moon's heavily cratered far-side. The origin of the Moon is usually explained by a Mars-sized body striking the Earth, creating a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternative explanations, and research continues into how the Moon came to be formed.
The Condensation Theory: This theory proposes that the Moon and the Earth condensed individually from the nebula that formed the solar system, with the Moon formed in orbit around the Earth. However, if the Moon formed in the vicinity of the Earth it should have nearly the same composition. Specifically, it should possess a significant iron ...
Oct 3, 2024 · The Moon isotopic composition is very near Earth composition, with giant impact models perfectly explaining that. It is moons that seems to have form with the planet’s formation that are expected to have an equatorial orbital plane, e.g. the Galilean moons that lies within 1 degree of Jupiter’s equatorial plane.
Jan 21, 2022 · The prevailing theory supported by the scientific community, the giant impact hypothesis suggests that the moon formed when an object smashed into early Earth. Like the other planets, Earth formed ...
Dec 13, 2022 · And this collision ripped apart early Earth’s crust. And that crust then coalesced. It snowballed into a whole separate entity, which we now call the Moon. So where did our Moon come from? Well, currently, our understanding is that the Earth had collided with a Mars-sized object named Theia. But once we send future astronauts to the lunar ...

Sep 26, 2024 · Earth’s moon orbits in a different plane. “The moon is more in line with the sun than it is with the Earth’s equator,” Williams said. In the alternative binary-exchange capture theory, the researchers said, Earth’s gravity separated the binary, snagging one of the objects — the moon — and making it a satellite that orbits in its current plane.
