The scientists found an evidence demonstrating the presence of another planet in the Solar System. It was the third ice giant that was located between the Saturn and the Uranus, and then it was thrown out of the Star System. The specialists from the Carnegie Institute of Sciences are studying this issue. They believe that in the past, another planet in the Solar System was located between the Saturn and the Uranus.
Before leaving it, its condition could be considered as embryonic. According to the hypothesized theory, that in the past the Sun was surrounded by a cloud of gas and dust. In that cloud, disordered collisions of elements took place, which marked the beginning of the formation of planets at a short distance around the parent star.
Then, those planets that turned out to be more massive launched a series of gravitational interactions. It led to the alignment of the planets in the order they are now. To get a clear picture of the past, the scientists created computer models and run nearly 6,000 computer simulations. Matt Clement, who is a senior researcher, noted that due to that approach, the scientists obtained data that there are thousands of planetary systems in the Milky Way galaxy.
But the Solar System is considered the strangest and most unusual, which confirms the process of reverse engineering and reproducing the processes of its formation. Studying the distant past of space, in which the star systems and planetary formations were created, the astronomers compare that process with finding out the circumstances of the accident, when the experts are trying to figure out how fast the cars were moving, their direction and what was on their way.
Computer simulations showed the final location of the Uranus and the Neptune that were believed to be the icy planets farthest from the Sun. Their location was determined by the mass of the Kuiper belt, a special zone of dwarf planets.
And also the mass of the exiled young ice giant, the lost planet of the Solar System. Having received such a model idea, the astronomers intend to use it for a new understanding of the formation of the terrestrial planets, including the existing one, in order to look for worlds in space that can accept life.
