The mysterious ‘Planet 9’ may have ‘escaped’ from the solar system

A new study offers possible explanations for how our solar system got its shape.

One recently released Study in Nature It provides – indirectly – evidence that our solar system is in its composition 9. Planets It could have been. follower”lost planetSo it could be “a gas giant They were as they occur in the outer solar system. This theory would go a long way toward explaining why our solar system looked the way it is today Salon.com Reports.

The team that wrote the study conducted about 14,000 simulations To find out how the solar system got into the shape we know. Simulations indicate that there is a file Instability In the orbits of the giant planets JupiterAnd the SaturnAnd the UranusAnd the Neptune and maybe”Planet 9“ I have given. The planets were originally much closer to the early form of Sun (to me Prostar) before strong fusion reactions take place on it. When it formed, gas and dust were expelled outward at the same time as the planets. This could have knocked “Planet 9” out of our solar system.

Scientists believe that these events brought about rapid and chaotic changes in the orbits of the planets. Seth Jacobson Manal Michigan State University, who was involved in the study, calls this a “global source of planetary instability in the galaxy.” So the instability must have happened much earlier beautiful model Adopted from 2005. In it, an attempt is also made to explain the migration of planets and the formation of orbits.

Controversy over the existence of ‘Planet 9’

The new simulations are not definitive proof that Planet Nine exists. However, they were able to show that the end result is similar – regardless of whether you start with 4 or 5 gas giants. In the same paper, the researchers deliberately did not want to delve specifically into the existence of Planet Nine because of the topic very controversial is being. “But we love talking about it with the audience,” Jacobson said aloud. SciTechDaily.

Scientists have been baffled by the possibility of a ninth planet at the outer edge of our solar system for a long time. While some studies of such a planet behind kuiper belt go outsideThere are also dissenting voices. other scholars say it comfortably no proof for the existence of Planet 9. While the researchers did not want to rule out the possibility that Planet 9 does not exist, they assume that it is much less likely than what the research has shown so far.
