The longest of the & # 39; object «Farout» in our solar system

(CNN) – For the first time, on the & # 39; an object in our solar system has been found more than 100 times the distance from Earth to the sun.

The Minor Planet Center of the International Astronomical Union announced the opening on Monday, calling 2018 a & # 39; VG18 object. But researchers have found what they call «Farout».

They believe that the spherical on & # 39; subject to & # 39 is a dwarf planet by more than 498 km in diameter, with a pink tone. This color is associated with a & # 39 objects, which are rich in ice and, given its distance from the Sun, it is not hard to believe. The researchers say that their slow orbit is likely to take more than 1,000 years to make the trip around the star.

The distance between the Earth and the Sun with 39 & # is astronomical unit or AU, approximately equivalent to 149 million kilometers. Farout 120 AU from the sun. Eris, next to & # 39 object far known 96 AU from the sun. For reference, Pluto 34 Hornet off.

On the & # 39; the object was detected C. Scott Sheppard of the Carnegie Institution for Science, David Tholen of the University of Hawaii, and Chad Trujillo of the University of Northern Arizona, not their first discovery.

The team there is looking for a higher size of the planet Earth on the edge of the solar system, known as the Nine Planet or Planet X, in 2014. The first proposed the existence of a possible planet in 2014 after being found "Biden" 84 UA. Along the way, they discovered a distant solar system, suggesting that the burden of something massive influence its orbit about the & # 39 objects.

Farout was found with the help of the Japanese Subaru Telescope 8 meters on Mauna Kea in Hawaii in November. The following observations with a telescope Magellan Observatory Carnegie Bells in Chile determined its trajectory, brightness and color.

"This discovery is a & # 39 is a truly international achievement in the field of research with the help of telescopes in Hawaii and Chile, operated Japan, as well as a consortium of research institutes and universities in the United States," said Trujillo in a statement. "With the new wide-angle digital camera in some of the biggest telescopes in the world, we finally exploring the fringe of our solar system, far beyond the orbit of Pluto."

In October, the team announced the discovery of "Goblin" 80 UA; This is so-called because the remote on & # 39; an object in the solar system was the first next Halloween.

It is unlikely that such a & # 39; objects are under the influence of gravity gas giants Neptune and Uranus, because you'll never get close enough to him, pointing out something else to determine their orbits.

Farout orbit has not yet been determined.

"2018 VG18 is much more distant, slower than any other observed on the & # 39; an object in the solar system, so it will take several years to fully determine its orbit," Sheppard said in a statement. "But he was in such a place in the sky other extreme of & # 39 objects in the solar system, suggesting that it may have the same type of orbit most of them. Orbital similarity shows many small and distant organs known Solar System was the catalyst for our initial assertion that there is a vast and distant planet several hundred AU around these small & # 39 objects.
