In a new study, which was done by some researchers, it said that the Pluto might have formed in the way somewhat different from the other eight planets in the solar system. Astronomers have changed the status of Pluto from Planet to dwarf planet, and they said that this planet might not be any partner at all.
The study which was done by scientists was published in the journal “Icarus” have claimed to found similarities between Pluto and the 67P comet which was studied by the European Space Agency’s (ESA) Rosetta spacecraft in the year 2004.
According to the Christopher Glein of Southwest Research Institute said in a statement, “We found an intriguing consistency between the estimated amount of nitrogen inside [a glacier on Pluto] and the amount that would be expected if Pluto was formed by the agglomeration of roughly a billion comets or other Kuiper Belt objects similar in chemical composition to 67P, the comet explored by Rosetta.”
When the NASA’s New Horizon spacecraft passed the Pluto in July 2015, the astronomers were able to get some data about the mysterious planet. When they have compared the New Horizon data with the 2016 Rosetta comet mission, the team has found that there is lot of comets which is similar to Comet 67P/ Churyumov-Gerasimenko which was visited by Rosetta and they stuck together which results in the celestial body, and it is similar in chemical composition to the dark Little Pluto.
The researchers have looked at the nitrogen-rich ice in the region of Pluto which is known as Sputnik Planitia. The lead researcher said in a statement that, we found an intriguing consistency between the estimated amount of nitrogen inside the glacier and the amount that would be expected if Pluto was formed by the agglomeration of roughly a billion comets or other Kuiper Belt objects similar in chemical composition to 67P, the comet explored by Rosetta.”Glein further said, “Our research suggests that Pluto’s initial chemical makeup, inherited from cometary building blocks, was chemically modified by liquid water, perhaps even in a subsurface ocean.”
In other to challenge them, SwRI researchers have tried an alternative theory for the Pluto origin, and it was speculated that the dwarf planet has formed due to very cold ices which have a chemical composition which is more closely matching with that of sun than comets.
