The researchers required performing digital simulations of our solar system for understanding as to how the discovered object happened to possess such weird orbit.
There are a couple hypotheses for what may have thrown its orbit off-kilter, but when researchers ran simulations on potential causes, they found that if they simulated a planet with properties like those proposed by a CalTech team in 2016, the orbit suddenly made sense.
The team called this object 2015 BP519, and its orbit around the sun is 35 to 862 times the radius of our planet's orbit around the sun.
The group from the Dark Energy Study state that 2015 BP519 is the most severe Trans-Neptunian Things discovered to this day in the paper. When system simulation was performed with just eight planets in the solar system, it did not tend to give the BP519 a similar kind of orbit, which it is having at the present.
There has been mounting evidence of the existence of Planet Nine for some time now. It used computer simulations of the solar system to figure out how the object may have come across this odd orbit.
For years, astronomers have talked about the discovery of a planet nine in our solar system. A strong and sustained interaction with Planet Nine appears to be the only way the new object could get such an erratic orbit.
But when they added a ninth planet with the characteristics of Planet Nine predicted by researchers, the numbers and orbits matched up.
He said: "It is not proof that Planet Nine exists". Guess what? The object's orbit matched nearly exactly. Astrophysicist Konstantin Batygin says that now, there are five line of observational evidence that point towards a ninth planet existing.
After that another paper was published saying that the orbit of Planet Nine may be pulling the planets 6° away from the equator of the Sun. Talking to Quanta co-author of the paper David Gerdes stated that this isn't really evidence that there is a planet 9 however that the existence of 2015 BP519 makes it most likely that there is a planet 9. There are also objects in the Kuiper Belt that orbit in the opposite direction as the rest of the objects in the solar system.
