More recently, at the end of last year, a Carnegie University astronomer Scott Sheppard (Scott Sheppard) and his colleagues discovered the most distant object known in the solar system. The dwarf planet Farout (2018 VG18) is 120 AU from the Sun. – 120 times farther than the Earth and 3.5 times farther Pluto. However, it took a while – and this record was broken.
The main objective of Sheppard and his team remains to detect a hypothetical big planet X on the far periphery of the solar system. So far, it is not possible to notice it, but it was this work that allowed the astronomers to see the position at 80 AU. Object Goblin, dwarf of Farout and now even more distant celestial body, which scientists have called Farfarout (from English. "Far, far"). "This is all for the press", Sheppard cited the presentation, which presented the discovery to colleagues, ScienceNOW.
According to astronomers, 4/5 of all objects known to date, rotating at a distance of over nine billion kilometers from the Sun, were found by Scott Sheppard and his colleagues. This work is expected to provide more reliable evidence for or against the existence of Planet X, whose attraction should influence the orbital movements of nearby celestial bodies. However, the orbits of Farout and Farfarout remain unknown.
