One of the most controversial events in the world of astronomy was when Pluto was removed from the list of planets in our solar system in 2006. But since then, many attempts have been made to find another object known as the Ninth Planet. One of the scientists who played a key role in removing Pluto from the list of planets has recently announced the identification of the orbital features of the ninth planet (Planet Nine) of the solar system. Astronomer Mike Brown from The California Institute of Technology says it has found more evidence of a potential planet in the Kuiper Belt, 4.3 billion kilometers from Earth. According to him, this mass is probably six times that of Earth and the fifth largest planet in our solar system. The International Astronomical Union called for a redefinition of the concept of "planet". "Once we discovered Eris and realized he was bigger than Pluto, we had to do something," he said. In fact, he feared that the possible existence of larger objects than Pluto in that range would eventually lead to a large number of planets, so he decided to change that trend by changing the definition of the planet.

This redefinition led to Pluto being classified as a dwarf planet. However, some scientists were not happy with the change. "He's wrong about Pluto," said NASA researcher Alan Stern of Brown's view. "Do we limit students to eight so that students do not have to memorize all 50 US states?" Ceres, Pluto, Haumea, Makemake, and Haumea. However, Stern and his colleague Konstantin Batigin (Konstantin Batygin), an astronomer at the California Institute of Technology who also works with Dr. Brown, are confident that their latest discovery is likely to be accepted as a non-controversial planet; Of course, if it turns out that it exists.Credit: CalTech/R. "At first we doubted its existence, but when we looked at its possible orbit and its effect on the outer part of the solar system, we were convinced that the planet was there," said Hurt (IPAC). There is. "There is gravitational evidence, but the search will not end until we have an image."

New computer modeling has now revealed new features of Planet 9. "The ninth planet most likely resembles an extrasolar planet from the supercontinent and is the closest thing to the properties of a typical planet in our galaxy," he said.
Is the ninth planet a black hole?
Researchers around the world have done a lot of research on the ninth planet, and there are various theories in this regard; One theory, published last year in Physical Review Letters, states that the ninth planet could be a black hole.
Another study published in 2018 provides more evidence for the ninth planet. According to this article, a Franpton object called 2015 BP519 has an unusual path due to being under the strong gravity of the ninth planet.
But Dr. Brown has been finding Announced a treasure map for the ninth planet. "Five and a half years after we proposed the existence of the ninth planet, we finally did what was most important to do the search," he said. "Now we know where to look."
In this recent study, in addition to the mass of the ninth planet, which is estimated to be 2.2 times the mass of Earth (2.2 +/1.3.3), details The large diameter of the planet's orbit around the sun and its inclination are also described.
According to Brown, these data provide only information about the orbit of the ninth planet and do not indicate exactly where the planet orbits. "The planet is probably at its farthest point from its orbit to the sun because it moves more slowly at the orbital peak," he added. "This is where we have to look."
He said of how the ninth planet formed: "Our best guess is that it formed near Uranus and Neptune and then approached Saturn or Jupiter, causing a gravitational effect." To be launched to the outer parts of the solar system.
