Earth has a large amount of water and a relatively large moon, which stabilizes Earth’s axis. Both are essential for life to develop on our planet. Scientists have now been able to show that water came to Earth with the formation of the moon.

Planetologists at the University of Münster (Germany) have now been able to show, for the first time, that water came to Earth with the formation of the Moon some 4.4 billion years ago. The Moon was formed when Earth was hit by a body about the size of Mars, also called Theia. Until now, scientists had assumed that Theia originated in the inner solar system near the Earth...

Lunar formation in the multiple-impact scenario. Moon- to Mars-sized impactors strike the Earth and leave a disk of debris orbiting the planet. The debris forms “moonlets” and migrate farther away from the Earth due to a tidal interaction, but eventually settle at a distance known as the Hill radius. Here, the moonlets merge to eventually form the moon..

The Moon, and the question of how it was formed, has long been a source of fascination and wonder. Now, a team of Israeli researchers suggests that the Moon we see every night is not Earth’s first moon, but rather the last in a series of moons that orbited Earth in the past. The newly proposed theory by Prof. Hagai Perets, of Technion, and Weizmann Institute Profs...
