NASA experts have found that the ninth planet exists at the edge of the solar system and weighs 5000 times more than Pluto

In 1930, Clyde TOMBO, a newly recruited observation assistant at Lowell Observatory, first discovered Pluto on the cold Arizona plateau after eight months of painstaking Sky Survey and careful comparison.

This is the first time that a new planet was discovered by an American astronomer using American observation equipment. It is one of the important events marking the transfer of the world science center from the European continent to the United States. Americans are proud of this and affectionately call Pluto the “American planet.”.

So far, it has been believed for quite a long time that there are nine planets in the solar system. However, in 2006, the International Astronomical Union gave a new definition of planets.

Planets are celestial bodies that orbit the sun (star). They have enough mass to make themselves round due to gravity, and they can clean up nearby small objects.

These three conditions need to be met at the same time in order to become a major planet, so Pluto is degraded to a dwarf planet. At the same time, there are only eight major planets in the solar system.

For years, astronomers have been debating whether there is an elusive planet outside Pluto

The ninth planet in the solar system

Researchers have discovered a distant rocky object that they believe has been attracted to a special orbit by an undiscovered planet. This finding supports an increasingly convincing view that the so-called ninth planet should exist.

The ninth planet was first discovered in 2016 by Caltech experts Michael Brown and Constantine butterkin. They found that six objects in the Kuiper belt on the edge of the solar system had strange orbits. Only 0.007% of this phenomenon happened by chance. After excluding other possibilities, they speculated that the cause of this phenomenon might be a real planet playing its gravitational role.

They found that the orbits of a group of cold bodies on the edge of the solar system were tilted, and said that these cold bodies were tilted by the gravity of the ninth planet in the solar system. The orbits of these celestial bodies are elliptical and point in the same direction, with an inclination of 30 ° compared with the plane in which the planets revolve around the sun.

Although the ninth planet has not yet been confirmed, many astronomers, including NASA scientists, have published many papers supporting this theory.

Among them, a research team from the University of Michigan described a distant object that they found in 2014, which is about the same size as a dwarf planet. The rock object called “2015 bp519” aroused the interest of the team. Because of the unusual inclination of its orbit to the plane where most celestial bodies in the solar system revolve around the sun, they used the solar system computer simulation system to study how its strange orbit is formed.

The simulator shows that the eight planets in the solar system will not make 2015 bp519 rotate in such an orbit. When the researchers added a ninth planet to the simulation system that matched the characteristics proposed by Caltech researchers, the simulation “reproduced” the current orbit of 2015 bp519, said David Geddes, an astronomer at the University of Michigan

“This can’t prove the existence of the ninth planet, but I can think that the existence of 2015 bp519 in the solar system supports the theory of the existence of the ninth planet.”

Although astronomers are still using telescopes to track down the ninth planet, the study adds to the evidence of its existence.

The mass of 2015 bp519 is about 5000 times that of Pluto, so its gravity is enough to affect the movements of several dwarf planets on the edge of the solar system. It has a fundamental interference with the movement of celestial bodies in the Kuiper belt on the edge of the solar system.

Computer simulations show that if the mysterious star really exists, its orbit will be more than 50 times the distance between the earth’s orbit and the sun, the researchers said in a statement.

In fact, because it is so far away, it takes 10000 to 20000 years for the planet to go around the sun.

At present, the latest study by astronomers from Sweden’s Rand University shows that the ninth planet is likely to be an exoplanet. They believe that in the early evolution period of the universe, when the planet moved closer to the sun, it was “stolen” by the sun. It is a part of the solar system that has not been detected so far, and it will become the first exoplanet found inside the solar system.

There are various hypotheses about why 2015 bp519 has not been observed. Some people think it’s still at the far end of the orbit, so it’s hard to find. Others believe that it is actually a small “black hole”, the size of a bowling ball, so it is difficult to find.

In any case, because its solar cycle reaches tens of thousands of years, and the last perihelion must have been in prehistory, even if human beings observed it at that time, there was no relevant record.

Xiaobian believes that if 2015 bp519 can be found, it will be a major victory for mankind. With the continuous development of science and technology, any planet, especially a planet whose mass may be 10 times that of the earth, will be found more and more easily.
