Discovered a New potential nano planet to the Boundaries of the Solar System: the object, which is found Beyond the orbit of Neptunehas been provisionally called 2017 of201has a diameter esteemed 700 kilometers And it runs around the sun along an orbita extreme that completes in 25,000 years. The discovery is announced on the Arxiv platform and has been made official by the Minor Planet Center of the International Astronomical Union e it could disavow the presence of a hypothetical and gigantic planet ninth still to be discovered, the so -called Planet x.
The new celestial body, potential cousin of Pluto, was identified by a group of princeton astronomers in 19 astronomical images captured over seven years by Victor M. Blanco Telescope and Canada France Hawaii Telescope.
“THE’aphelion of the object, that is, the point of the orbit farthest from the sun, is Over 1,600 times further than the earth’s one – observes the researcher Sihao Cheng – while his perihelionthat is, the closest point, is 44.5 times further than the terrestrial onesimilar to that of Pluto “. This extreme orbit suggests one complex history of gravitational interactions. “He must have had close encounters with a giant planetwhich caused its expulsion on a broad orbit, “says the researcher Eritas Yang.” There may have been more than a passage in his migration. It is possible that this object was first expelled in the cloud of Oortthe most distant region of our solar system that hosts numerous comets, and then postponed back“.
“Many extreme transnettunian objects have orbits that seem to be grouped into specific orientations, but 2017 of201 is an exception“, says Jiaxuan li. If the grouping of the orbits of many transnettunians has been repeatedly interpreted as an indirect proof of the existence of another large planet in the solar system (the planet X or the platform nine) which leads these objects, gravitating, The 2017 Of201 anomaly could question this hypothesis.
The discovery of the new celestial body has significant implications for understanding the external sun system, because its presence could indicate that the area beyond the Kuiper belt is not as empty as it was thought. According to Cheng “there may be another hundred other objects with orbit and similar dimensions, they are simply too far away to be detectable now. Even if the progress in telescopes have allowed us to explore remote parts of the universe, there is still a lot to discover on our solar system”.
