Astronomers descovry something amazing: Planet 9
The alleged object, which has not yet been directly observed, was named Planet 9 and had a mass of about 10 times larger than Earth and 5,000 times respectively larger than Pluto. This planet should have an orbit 20 times more elongated than that of Neptune, which is an average distance of 4.5 billion kilometers from the sun.Thus, Planet 9 should achieve full rotation around the Sun in a period of 10,000 to 20,000 years, according to researchers Konstantin Batygin and Mike Brown of the California Institute of Technology, who made this discovery from the analysis of mathematical models the orbits of the planets known in the computer simulations.

If the existence of this planet will be confirmed, our solar system will return to the 9 planets, as it was before switching category dwarf planet Pluto.There are still many things in our solar system waiting to be discovered, which can only make us happy.Astronomers looking transneptunian hypothetical planet since the late nineteenth century, but the hypothesis of the existence of this mysterious planets were refuted by data collected missions probes Pioneer 10, Pioneer 11, Voyager 1 and Voyager 2. It remains to be seen whether study by two American astronomers will lead to the discovery of the alleged planet.
They were more reserved choosing simple name for this object Planet 9 has not yet been directly observed. If the existence of this planet will be confirmed, our solar system will return to the 9 planets, as it was before switching category dwarf planet Pluto.Astronomers say they have evidence of a planet 10 times more massive than Earth, located in an orbit about 20 times farther from the Sun than the planet’s number 8 Neptune is located at an average distance from the Sun. 4.5 billion kilometers. The planet 9 would achieve complete revolution around the sun in a period of up to 20,000 years.Although it was seen directly, the two scientists are optimistic, claiming that it is a matter of time before this discovery will make the announcement at one or terrestrial observatories in orbit. From antiquity to the present it has been discovered only two planets in our solar system, and this would be the third. There are still many objects in our solar system waiting to be discovered, which can only make us happy, commented Mike Brown, lead author of the study along with his colleague Konstantin Batygin. Planet 9
The study bases its findings on computer simulations that took into account the unusual orbits circumsolare they have some of the largest objects in the Kuiper Belt, the belt of asteroids, comets and planetoids that lies beyond the orbit of Neptune. Specifically, six such objects moving around the Sun in elliptical orbits which are directed in the same direction, even if each of these objects is moving through space at different speeds. In addition, the orbits of the six items transneptunian have the same angle of 30 degrees with respect to the plane of the orbits of the eight planets relatively known in our solar system.).In percentages, the chances that the orbital plane of the six objects have this feature by chance are only 0.007%, which is virtually non-existent. Simply this can not be happening, so we thought it might be something else out there, far away, which caused the orbits of Kuiper Belt objects.Further skeptics, Brown and Batygin took into account the likelihood that relatively small objects in the Kuiper Belt might influence the orbits of objects studied. But after switching to calculations, they understood that if that were the case, then all objects in the Kuiper Belt should have a mass 100 times greater than it actually is. Planet 9
Consequently, the two went to checking other assumptions – there is a large planets would lie beyond the Kuiper Belt, which would be printed these six items transeptuniene unusual orbits moving.Computer simulations have been conducted to verify this hypothesis confirmed the existence of the mysterious Planet X. They can proved that gravitational attraction would be exercised by a planet about 10 times more massive than Earth, what would move in an orbit “anti -aliniată could explain these bizarre orbits of the six Kuiper Belt objects.Moreover, as noted by then, the existence of so-called Planet 9 “may also explain the orbits of distinct two dwarf planets in the Kuiper Belt, Sedna, respectively, 2012 VP113. The same computer simulations have predicted that some items Belt Kuiper should have orbits tilted relative to the plane perpendicular to the orbits of the eight known planets in our solar system. Four such objects have been discovered recently transneptunian, which confirms again, although more indirectly, the existence of Planet 9.
We introduced these calculations positions objects and their orbits and matched perfectly with simulation results. When I discovered this, I was gaping in astonishment.When the simulation conducted aligned distant Kuiper Belt objects and objects like Sedna generated, seemed something extraordinary – because I managed to hit two birds with one stone. And as the existence of this hypothetical planet would explain these orbits perpendicular, then I not only hit two birds after I threw a single stone, but I hit a third bird which does not even know was in a nearby tree.Planet 9 could be formed closer to the Sun, but then was thrown into the outer solar system after Jupiter or a gravitational interaction with Saturn, the giant planets of our solar system. If Planet 9 will be discovered, it would answer many questions about the formation and evolution of our solar system.One of the discoveries we made while observing other solar systems is that most planets have masses between the Earth and Neptune’s. Until now I thought that our solar system contains such a planet that is almost ubiquitous in other solar systems that we studied. We might not be quite so different from what I thought. Planet 9
Meanwhile the two astronomers using other colleagues went behind telescopes in search of the mysterious planet. Its orbit was determined using the computer, but its exact position, today, on this orbit is not known. Brown is optimistic, considering that there is a good chance to be discovered.Mike Brown discovered alone or together with other colleagues transneptunian several objects, including dwarf planets Sedna and Eris, discoveries that have had an important role in the decision by astronomers to reclassify Pluto to dwarf planet category.
