Computer simulations performed by astronomers at the University of Oklahoma show Where to look for signs of a hypothetical ninth planet. Indirect evidence of its existence came in 5 years ago, Professors Konstantin Batygin and Mike Brown from Caltech (Caltech). Since then, new data and hypotheses have emerged about it, and the effects of Planet X – as it is also called – have also been inspected in medieval manuscripts. There is even a hypothesis that it orbits the solar system Ur -black hole Not the ninth planet.
Batygin and Brown suggested the existence of nine based on their study of the unusual orbits of the 6 most distant Paas Kuiper objects. In recent years, various research teams have found several trans-Neptunian objects (TNOs) —that is, outside Neptune’s orbit — whose unusual orbits can be explained by the influence of Planet Nine on them. Batygin and Brown assume that the mass of Planet X is ten times that of Earth, that it is very far from the planet Neptune, and that its orbit around the Sun lasts from 10 to 20 thousand years. It is very difficult to monitor such a thing. Remember that planets do not shine with their light. Therefore, for years, scientists have been trying to figure out where to look for the ninth in the sky.
Kaley Anderson and Nathan Cape enter ARXIV their work they modeled the evolution of the solar system. In the model, they took into account the presence of four giant planets (Jupiter, Saturn, Uranus, Neptune) and millions of “particles” representing the Kuiper Belt. They simulated four billion years of evolution of the solar system. In part of the simulation, they took into account the presence of eight known planets, and on the other hand, they added a ninth planet with different orbits to this system. In each simulation, millions of “particles” felt the impact of the plants as Neptune traveled through the disk. Eventually, as a result of this process, the disk scattered and created a Merchant Belt simulation that we can compare to the already observed beltSays Anderson.
In models responsible for the existence of Planet X, distant Kuiper belt objects tended to accumulate in orbits with a relatively low slope (mile) relative to the plane of the solar system. These objects were very far from the sun, no closer than 40-50 astronomical units. It is important that simulations involving only 8 known planets did not occur TNO accumulation in such orbits. This, in turn, suggests that if we find the TNO far away in orbits with a slight slope to the plane of the solar system, it would be another indication that the ninth is there.
This is a very good study that shows how to observe the consequences of an unknown large planet, says Cat Volk from the University of Arizona, who is working on the Outer Solar System Origins Survey (OSSOS) project.
The researcher says that we can actually search for TNO with orbitals described by Anderson and Kaib, but it is not easy because such objects are very poorly visible. With the technology available at the moment, we need to find a balance between how far we can see inside the solar system and how wide the sky we can see. But in the coming years, our observation capabilities will increase significantly thanks to the Vera C. Rubin Observatory being built in Chile, which will start operating in 2023.
It will be a revolution as the telescope will be able to detect TNO remotely as specialized projects like OSSOS, and at the same time will be able to observe large areas of the sky. I think this telescope will show us many of the TNOs that Anderson and Kip have proposed.
