Researchers estimate that the enigmatic planet X may be the cause of a certain ‘wobbling’ in the Solar System, it seems to have caused the Sun to be slightly inclined.
Researcher Percival Lowell in 1906 call it Planet X, at that ti,e it was just a hypothetical planet, whose possible existence in the outer reaches of the solar system was the subject of academic debate and search for through astronomical instruments, between the late nineteenth century and the first decades of the twentieth century.
Several astronomers estimated then, that an unknown body was found just beyond Neptune, the most distant planet known at that time.
This may explain certain disturbances of the orbits which brought on the “ice giants” Uranus and Neptune, which were not understood the influence of others planets had in the solar system and the masses that were attributed to these celestial bodies, according to the data available at that time.
Batygin who is professor at The Planetary Of Science sated that “It continues to amaze us; every time we look carefully we continue to find that Planet Nine explains something about the solar system that had long been a mystery”.
Discovery Of Pluto
Pluto was discovered in 1930 by a follower of Lowell thanks to the search for Planet X. Pluto was with much less mass than expected and could not disturb the orbits of the “ice giants”. Lowell had calculated that Planet X would have a mass equivalent to 6.6 times that of Earth, while Pluto had less mass than the Moon.
A blow to the foundations of the hypothesis came from new measurements from the space probe Voyager 2, which corrected previous estimates of the mass of Neptune. The new numbers alone explain the so called “disturbances” of Uranus and Neptune orbits, so they seem to have confirmed a Planet X to justify both celestial mechanics.
Later they began to discover other celestial bodies, like Eris, Makemake and Haumea in the outer solar system. These have been listed in 2006 along with Pluto as dwarf planets and the subcategory of plutinos. Considering its location they have also have been called trans-Neptunian objects, but do not match the mass and orbital characteristics that were once predicted for the so-called “Planet X”.
“Because Planet Nine is so massive and has an orbit tilted compared to the other planets, the solar system has no choice but to slowly twist out of alignment,” says Elizabeth Bailey, who is a graduate at Caltech leading the study announcing this discovery.
In the context of these recent findings however they have emerged new hypotheses related with the idea that led to the search for Planet X also to the discovery of Neptune. The indirectly suspecting the existence of other worlds in the solar system from the analysis of the orbits of the known bodies. Scientific theories are still circulating as the Nemesis hypothesis and the hypothesis of Tyche.
The debate on the possibility of a large body incognito in the solar system was fueled by the unusually elongated orbit of the trans-Neptunian object Sedna, discovered in 2003 and even more information was brought to light in 2016 with the recent paper published by Mike Brown, one of the team members that discovered Sedna and Eris in defending the probable existence of a Giant Planet X with dimensions of between 2 and 4 times the diameter of the earth.
The search continues.
