A team of astronomers under the leadership of Michelle Bannister from Belfast University in the UK found beyond the orbit of Neptune large celestial body with an unusual orbit. The outer diameter of the object, called 2010 JO179 was quite impressive for a dwarf planet and is about 900 kilometers.
Discovered a dwarf planet, like many other such facilities located in the Kuiper belt — distant regions of the Solar system like the asteroid belt, but is about 20 times wider and dozens or even hundreds of times more massive. Astronomers say that compared to other cosmic bodies in this area 2010 JO179 is fairly bright object.
The orbit of the space object has two characteristics. First, it is unusually strongly “tilted” relative to the plane of the Ecliptic at which the Sun revolves around the vast majority of cosmic bodies. That’s one of the reasons why the dwarf planet, despite its brightness, were only detected now. The scientists also draw attention to the fact that the orbit is elongated JO179 2010 — the minimum distance from the dwarf planet to the Sun is 5.8 billion kilometers and a maximum of 17.5 billion kilometers.
Day on the dwarf planet last around 30 hours a year — about 700 “terrestrial” years. Experts say that five revolutions around the sun 2010 JO179 requires as much time as Neptune — 21 turnover, and it is, in all probability, is not a mere coincidence but the result of ancient migrations, the ice giant. Moreover, researchers do not exclude that this fact indirectly will help you to better understand how large “outer” planets of the Solar system influenced the formation of the Earth.
Yet an article on the new dwarf planet, has published not one peer-reviewed publication, but its Preprint available in electronic library arXiv.org.
