After more than a hundred years of searching for a mysterious planet in the solar system, two astronomers from the California Institute of Technology announced in 2016 that they had discovered evidence of a hypothetical ninth planet.

These two astronomers, Mike Brown and Constantine Batygin, talked about the existence of a giant ice planet outside the orbit of Pluto, but it is within our solar system, and that its mass is between 5 to 10 times the mass of Earth, but they did not visually recognize this planet “X”, and discovered its existence through The movement of dwarf planets and other smaller celestial bodies discovered in the outer regions of the solar system!

This mysterious planet was previously known as the tenth planet, but it is called the ninth planet after Pluto was stripped of its planet status in 2006.

The search for the supposed “X” planet has been going on for more than a hundred years, and many astronomers believe that it simply does not exist. However, according to Batygin and Brown’s observations, there is another celestial body orbiting the sun in addition to the known planets.

And the search for the mysterious planet is the Kuiper belt region, where scientists are trying unsuccessfully so far to find the ninth planet.

Basically, the searches were related to the Kuiper belt, which is a group of trans-Neptune objects, the largest of which is Pluto, and many large objects in the Kuiper belt were repeatedly called the name of the unknown planet, but the matter was not confirmed as it was not found that any of these objects are larger than Pluto.

The planet of these two astronomers is ten times heavier than Earth, while its orbit around the sun seems incredibly long, about 15 thousand years. The minimum distance of the planet from the sun is 200 astronomical units, or 200 times more than the Earth is in relation to the sun, while the maximum ranges from 600 to 1200 units.

The two scientists found clues to the new hypothetical planet while studying the orbits of six large Kuiper Belt objects whose trajectories suggest they are subjected to an undetermined gravitational force. In their studies, they concluded that there was only a 0.007 percent chance that these features were a fleeting coincidence.

The two astronomers indicate that what they have reached is just a hypothesis, while Brown asserts that the possibility of proving the existence of the ninth planet in the solar system comes only through the visual method, and Brown and Batygin assume that such a matter will take about five years of searching for the planet using telescopes, and even then from the previous It is too early to say that the solar system has been joined by a ninth planet.
