Formation of the moon brought water to Earth

As the only terrestrial planet, the Earth has a large amount of water and a relatively large moon, which stabilizes the Earth’s axis. Both are essential for life to develop on Earth. Planetologists from 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. The results are published in the current issue of the journal Nature Astronomy.
