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.
Artist's depiction of a collision between two planetary bodies. Such an impact between Earth and a Mars-sized object likely formed the Moon.. The giant-impact hypothesis, sometimes called the Theia Impact, is an astrogeology hypothesis for the formation of the Moon first proposed in 1946 by Canadian geologist Reginald Daly.
In 2021, the Declaration of the Rights of the Moon [318] was created by a group of "lawyers, space archaeologists and concerned citizens", drawing on precedents in the Rights of Nature movement and the concept of legal personality for non-human entities in space. [319] [320]
Theia, an ancient planet, collided with Earth to form the moon, scientists believe. A new study suggests Theia could have also formed mysterious blobs called large low-velocity provinces, or LLVPs.
The Moon formed after a collision 4.5 billion years ago between the young Earth and a Mars-sized object, called Theia - but what happened next?
The huge indent, called the 'imbrue basin,' stretches across 750 miles.
Made a closest approach of 1,950 kilometres (1,210 mi) on 18 September, and circled the Moon before returning to Earth. Landed in the Indian Ocean on 21 September at 16:08 UTC, becoming the first Lunar spacecraft to be recovered successfully and carried the first Earth life to travel to and around the Moon.
