Looking for the 9th legendary planet that was “ruthless” knocked out by the sun-Information Technology

New research into what happened to the “gas giants” of the early solar system continues to reveal clues to the legendary “ninth planet”.

“Our solar system was not always what it is today. According to its history, the orbits of the planets have completely changed” – Associate Professor Seth Jacobson from Michigan State University (USA) and colleagues associates from France and China said.

According to SciTech Daily, this group of scientists has just published a new theory that could help solve the mystery of how the solar system evolved, specifically how the “gas giants” – Jupiter, Stars Saturn, Uranus, Neptune and even a fifth gas giant disappearing in and out of the “9th planet” – is in its current position again.

We have observed many other planetary systems, in which the gas giants are located much closer to the parent star than the gas planets in our world. That is a mystery.

To answer that, the team revisited the famous Nice model (developed in Nice – France), which shows that there is an instability among these gas giants, a chaotic collection of gas giants. gravitational interaction in which the appearance of 5 new gas giant planets is enough, instead of 4 as we already know.

Newer evidence, just published in Nature, based on data found in lunar rocks, provides valuable data for the “inner solar system” region where the rocky planets Mercury are located. , Venus, Earth and Mars reside.

The results show that it was the rapid evaporation of the protoplanetary disk that pushed the gas giants – which initially orbited very close to the Sun – very far away. This process occurs when the young Sun “matures”, flares up and begins to burn nuclear fuel, heating the protoplanetary disk and blowing it from the inside out, propelling the giants away.

Based on current models of the orbits and interactions between the gas giants, it is very likely that there were as many as five gas giants during that period of ancient chaos. But so far, there may be only 4 because the strong thrust of the Sun has caused the ninth planet, the outermost, to be… thrown out of the solar system.

But it does not rule out the possibility that it is still there but has stopped at a very distant orbit – 50 billion miles from the Sun, as the original Nice model shows. Several studies over the last few years have also pointed to the mysterious interactions experienced by objects at the edge of the solar system, suggesting that something massive, with strong gravity must be wandering beyond the solar system. dark.

The “cruel” push of the solar system has created conditions for a peaceful region to be formed, the “inner solar system”, where 4 rocky planets were born, of which up to 3 are in the habitable zone of the solar system. systems are Venus, Earth and Mars.

According to Associate Professor Jacobson, they did not highlight the controversial 9th ​​planet in the paper but still wanted to tell the public about it, about the new data. According to him, humanity will soon have the answer.

The Vera Rublin Observatory (under construction in Chile with the main task of carrying out the “Space-Time Heritage Survey”), scheduled to operate at the end of 2023, is said to be capable of capturing signals sign of the ninth planet if it is indeed there.
