There are several theories about where actuallytook the moon. Our best guess is that the moon was formed when a large object, known as Theia, hit the Earth. As a result of the collision, a huge amount of debris was thrown into orbit, which eventually merged into one and formed the Moon. But this theory has a problem.
Mathematical models show that largepart of the material that formed the moon was supposed to come from the object that flew into it. But the samples obtained during the Apollo missions show that most of the lunar material came from Earth.
How did the moon form? From earth magma!
The work that appeared earlier this week inNature Geoscience offers a possible explanation. The study shows that the Earth at the time of impact was covered with hot magma, and not solid outer crust.
Magma is easier to dislodge from the surface than solid bark, and this means that it would be easier to throw material from the Earth into space, and it could later harden on the Moon.
This theory depends on time.formation of the moon. The earth must be warm for the magma to take on the necessary form, and then the theory will work. In addition, the new simulation still does not meet all the criteria by which the observations of the moon will correspond to our theories. But this is an important step in the right direction.
I wonder if this theory will affect the study of the origin of the Martian satellites?
The latter theory states that Phobos and Deimoswere to appear after the collision of Mars with the ancient body is three times smaller than the Red Planet, after 100 to 800 million years after its formation. According to scientists, the debris from this collision formed a very wide disk around Mars, consisting of a dense inner part of the merging substance and a thin outer edge mainly of gas. In the inner part of this disk, the moon was formed a thousand times smaller than Phobos, which has since disappeared. The gravitational influence exerted on the external disk gradually led to the fact that the debris in it gathered in other, small and distant moons. After several thousand years, Mars was surrounded by a group of about ten small satellites and one larger satellite. After a few million years, as soon as the debris disk cleared, the tidal effects of Mars returned most of these satellites to the planet, including the one that was larger. Only two small moons remained, Phobos and Deimos.
