“The Goblin” is a new small planet discovered by chance over Pluto. His very long orbit would be a further indication of the existence of the hypothetical Planet nine.It would seem that beyond Pluto there are a lot of new worlds to discover. The last sighted is the Goblin, a planet of only 300 kilometers in diameter and very far from the Earth, which completes an orbit around the Sun every 40 thousand years! Yes, you understood well, 40 thousand years, not like the earth, which takes us approximately 365 days! So very difficult to observe. The Goblin was discovered somewhat by chance, trying to spot the very famous and hypothetical Planet nine, the gigantic celestial body that would influence the orbit of objects on the border of the solar system. And from the Minor Planet Center of the International Astronomical Union that believe that the particular orbit of The Goblin would be a further indication of the presence of the mysterious planet nine. This plant is very far from us, far beyond Pluto: think of the distance between the Earth and the Sun (which is an astronomical unit for the astronomers, Ua) and multiply it by 80. It has an orbit to say the least stretched, so much so that 40 thousand years to make a single turn approaching the Sun no more than 65 UAs. Being so distant and small it was a stroke of luck to be able to see it. The Goblin happened by chance in the objectives of the Subaro, Magellan and Discovery Channel telescopes, which are located in Hawaii, Chile and Arizona respectively while looking for the mysterious Planet Nine, the gigantic celestial body that would influence the orbit of the objects of the System external solar. It took several years to learn enough about him and his orbit, but it seems that it was worth it because the data would be consistent with those of other small planets observed previously and would fit perfectly with the theory of the existence of a Supermassive planet X whose gravity affects the orbit of other smaller celestial bodies.The Goblin, is not the only distant planet captured by our instruments that has peculiarity of the orbit. Just think of Sedna or 2012 VP113. Tholen comments “We think there may be thousands of small bodies like the 2015 TG387 at the extreme limits of the Solar System, but their distance makes them difficult to find” .“These objects of the so-called Inner Oort Cloud, like 2015 TG387, 2012 VP113 and Sedna, are isolated from most of the known mass of the Solar System, which makes them immensely interesting,” Sheppard explained. “They can be used as probes to understand what is happening at the margins of our solar system. These distant objects are like bread crumbs that lead us to Planet X. The more we find, the better we can understand the external Solar System and the hypothetical planet that we think is modeling their orbits “.
A discovery that would redefine our knowledge of the evolution of the solar system. Only the umpteenth clue that something big must necessarily be! But man today, with the technologies at his disposal, reaches up to a certain point. Surely we would discover other planets that could be hospitable or not for the man and who knows, maybe already inhabited!
