Perhaps the solar system has nine planets. Two scientists from the United States believes that the deployment of the orbits of several objects beyond the orbit of Neptune indicates the presence of a large, unknown planet on the edge of our solar system.
A hypothetical planet can circle the Sun once every 10-20 thousand years within an average of twenty further than Neptune. Her weight would be 10 times greater than the mass of the Earth.
So say Konstantin Batygin and Michael E. Brown of Caltech in Pasadena Institute (USA), experts from research of distant objects in the solar system and the authors of the article, which appeared in the journal “The Astronomical Journal.” New potential target scientists named the Ninth Planet (Planet Nine).
This may be true ninth planet. Since ancient times, it was discovered only two real planets in the solar system and it would be the third. It is quite a significant portion of the solar system, where you can still discover something interesting
- Says Michael Brown.
His hypothesis, researchers are based on the analysis of clusters of six known objects orbiting beyond Neptune. According to calculations carried out, there is only 0.007 percent. chance (one in 15,000) that the observed characteristics of the orbits of these objects are accidental convergence.
This is part of the on-going for over 100 years searching for the so-called. Planet X, which is a large object beyond the orbit of Neptune, disturbing the movement of Uranus and Neptune. The observations led to the discovery of Pluto in 1930, but soon found out that Pluto is too small to explain the disorder. Despite the fact that studies in the second half of the twentieth century, made it possible to specify the mass of Neptune, so that the problem of disorder disappeared, the objects beyond Neptune still sought.
It is now known that beyond the orbit of Neptune is a lot of small bodies, similar to asteroids between the orbits of Mars and Jupiter. The equivalent of the asteroid belt is called the Kuiper belt.
The Role of Brown as the discoverer of a potential ninth planet, contrasts with his earlier role “detronizatora Pluto”, because the discovery by Brown in 2005 dwarf planet Eris was one of the arguments for titres deprivation ninth planet Pluto Solar System. In 2006, the International Astronomical Union has established a definition of a planet in the solar system, according to which it has eight planets from Mercury to Neptune, and Pluto and several other objects are assigned to a new category called. dwarf planets, ie intermediate bodies between asteroids and planets.
Brown together with Batyginem analyzed by a year and a half distant objects in the Kuiper belt, approaching the problem from two different perspectives. Brown as an observer looking from the perspective of what you see in the sky and Batygin as a theorist analyzing the dynamics of physical solutions in the orbits of objects in the solar system.
The existence of a ninth planet helps explain not only the inclination orbits in the Kuiper belt objects. It also allows you to explain the mysterious orbits of two of them. The calculations also show that in the Kuiper belt may occur with orbits lying perpendicular to the plane of the solar system. It turns out that in recent years, observers have identified four subjects moving vertically in relation to the movement of Neptune. Their orbits are in line with expectations simulated taking into consideration the Ninth Planet.
How can originate ninth planet? If, four giant gas planets, there is no reason to think that she could not have formed as fifth. If you came too close to Jupiter and Saturn, may have been stranded on a long elliptical orbit.
Some experts, however, has doubts and indicates that the statistical uncertainty of the results is still higher than generally accepted in scientific research, and the reduction of group analyzed objects from 13 to 6 weakens the conclusions. Batygin and Brown speak in turn, they realize that astronomers generally recognize the existence of Planet X until when will direct observational discovery of the object, and now it is still only a hypothesis. Astronomers have obtained observation time on the large 10-meter telescope in Hawaii to look for this planet.
