The solar system acquired its current form almost immediately after the formation

The hypothesis that the solar system originated from a giant cloud of gas and dust was first proposed in the

in the second half of the 18th century by the German philosopher Immanuel Kant and was further developed fromFrench mathematician Pierre-Simon de Laplace.

Now this is a consensus among astronomers, however inThere are discrepancies between scientists in some details. Until recently, it was believed that the solar system acquired its current properties as a result of a period of turbulence that occurred approximately 700 million years after its formation. However, some of the latest studies show that it formed in the more distant past, at some stage during the first 100 million years.

Simulations conducted by astronomers have shown that the solar system in its current form formed within the first 60 million yearsFirst from the clouds of gas and dust that surrounded the Sun for about 4.6 billion yearsThe giant planets Jupiter, Saturn, Uranus, and Neptune formed in their orbits closer to each other and to the star than they do now.

We first created the primary sculptureplanetesimal disc. To do this, we had to return to the formation of the ice giants Uranus and Neptune. Computer modeling based on the model we constructed in 2015 showed that the formation of Uranus and Neptune may have been the consequence of the formation of planetary nuclei with a mass of several terrestrial ones. The novelty of this study is that the model does not start with fully formed planets. Instead, Uranus and Neptune are still in a growth stage, and the driving force behind this process is two or three collisions involving objects of up to five Earth masses.

Earlier scientistsfound outthat the Earth 3 billion years ago was completely covered by the ocean. For several eras, there was not a single large land area on the entire planet.
