At the very edge of our solar system, a new dwarf planet (2012 VP113), which is located far beyond outside the orbit of Pluto. Astronomers suggest that perhaps this little-studied area of the cosmos contains millions of undiscovered objects, including planets whose sizes are larger than our Earth. Scientists recognized the found celestial body as a dwarf planet. Besides Moreover, they suggest that this planet was pulled by an orbit another, larger planet, which is still not being considered. For several decades, astronomers conditionally divided The solar system is in three main parts. Inner zone which contains rocky planets such as Earth and Mars. Middle Zone – the kingdom of the gas giants of Saturn, Jupiter, Uranus and Neptune. External zone – Kuiper Belt, which is inhabited by distant ice worlds, such as Pluto. Sedna’s discovery, which took place in 2003, demonstrated that this card is incomplete. Planet Sedna whose diameter is about 1000 kilometers, does not have elliptical orbit. Therefore, Sedna cannot approach the sun closer than 76 au (one AU – the distance from the Earth to the Sun, which is about 150 million km). Maximum distance Sedna to the Sun is approximately equal to 940 AU Such remoteness says that Sedna is in far outer limits Solar system. For comparison, the distance between the orbit of Pluto and the Sun varies from 29 to 49 AU Today astronomers are sure that Sedna is not the only celestial body of its kind. Discovered planet 2012 VP113 – direct proof of this. Body 2012 VP113, made of ice, has a diameter of 450 km and is not suitable closer to the Sun than 80 AU Such distant objects as Sedna and The 2012 VP113 is incredibly hard to spot. Astronomers suggest that in this far-off region of space there may be more than 900 bodies larger than Sedna, as well as trillions of comets. Some of the outer space objects may compete the size of Mars or even Earth, scientists say. However with With the help of modern technologies, it is still difficult to detect and study them. Astronomers do not know the exact origin and history of Sedna’s evolution and 2012 VP113. Perhaps these objects were formed much closer to The sun and then were displaced by gravity interactions with other stars. Perhaps their bodies pulled the “star sister” of our Sun, born of its cluster. Or Oort cloud’s internal objects pulled these planets from neighboring star system. Some experts believe that the characteristics orbits of Sedna and 2012 VP113 suggest that these bodies attracts a planet 10 times larger than our Earth. Such the assumption is not evidence that the planet X actually exists, but this cannot be denied. Total the picture should become clear with the discovery of other internal objects Oort clouds. Studying these objects will allow astronomers more learn about the origin and evolution of the orbits of these mysterious, cold and remote space bodies.
