An international team of astronomers has discovered a month earlier, a new dwarf planet. As a result, the total number of minor planets in the Solar system now stands at 27.
Recently found dwarf planet, dubbed 2015 RR245, was spotted in the outer Solar system during the study, scientists from OSSOS. Activities OSSOS is to compare a huge number of items created from ice and rock that form huge Kuiper belt beyond the orbit of Neptune.
It turns out that the icy worlds beyond Neptune formed as the giant planets, and then moved away from the Sun. They have allowed researchers to piece together the history of our Solar system. Almost all of these icy worlds is painfully small and weak, but the purpose of experts is to detect the brightest of them. During the year, the spacecraft NASA made flown past Pluto. Astronomers were able to catalog about 600 Kuiper belt objects, including 100 of them, which one day may be classified as a dwarf planet.
Listed as a dwarf planet an object that orbits the Sun and is large enough to allow gravity to make it round. Not so long ago managed to establish that the dwarf planet in 2015 RR245 moving around the Sun more than 700 years old, has a size of about 700 km. Scientists said when the dwarf planet Eris bigger than Pluto, was discovered, the question arose on the appointment of the ninth planet of the Solar system. It was decided that Pluto actually belongs to the dwarf planets and the Kuiper belt can be called a full-fledged planet.
Currently, the international astronomical Union recognizes only five objects as dwarf planets: Pluto, Ceres, Haumea, Makemake and Eris. New dwarf planet in 2015 RR24, was first spotted in February of this year, and its existence was confirmed a few weeks ago. It is impossible to directly measure the parameters of the dwarf planet, because it is far from the sun, but scientists believe that its width reaches from 370 to 500 miles. Workers OSSOS believe that such knowledge will help to reveal information about the formation of planets and the sun.
By the way, a Professor of planetary astronomy at the California Institute of technology Michael brown, could see the dwarf planet Eris, which has called into question the activities of Pluto as a planet.
