Moon formed ‘just hours’ after planetary collision?! Simulation video released – Nazology

how was the moon made?

Astronomers, 1969 7moonThe Apollo 11 mission provided the first clues about the birth of the Moon.

A 21.6-kilometer lunar rock and dust sampleEarthwas brought back to

The sample was about 4.5 billion years old, and it was estimated that the moon was born about 150 million years after the formation of the solar system.

In addition, the lunar rock composition is similar to that of the Earth, the orientation of the Earth’s rotation and the Moon’s orbit are similar, and the lunar samples are virtually free of volatiles and light elements (which are suggesting that the Moon was formed under extremely high temperatures that vaporized it).

From there, the “Giant Impact Theory” emerged, which states that a protoplanet collided with the early Earth.

This hypothetical protoplanet is named “Theia” after the Greek goddess Theia (mother of the moon goddess Selene).

There is a possibility that the “ protoplanet Theia ” that caused the giant impact is buried in the Pacific Ocean

On the other hand, we don’t know exactly how the collision between Earth and Theia occurred and what processes followed.

In the conventional hypothesis, when Theia collided with the earth,The impact shattered Theia into countless pieces, which cooled over millions of years as it orbited the Earth, forming the Moon.It is said.

But if the Moon is largely made up of Theia, it doesn’t explain why much of the current Moon’s composition is so similar to Earth’s.

Some experts believe that the collision with Thea destroyed much of the Earth, and much of that debris was used to form the Moon.

However, in the event of a major collapse of the Earth, the current Moon and Earth would follow completely different orbits.

With the aim of answering these questions, the research teamsimulationThe we.
