New evidence for the existence of the ninth planet

Astronomer Mike Brown, at the beginning of the year, told about obtaining indirect evidence of the existence of the ninth planet in our Solar System, announced the receipt of a new confirmation of its existence . In the Kuiper belt, another object was found whose behavior can be explained by the gravitational influence of Planet X.

In January 2016, Brown and his colleague Batygin published a paper in which they showed that the movement of six Kuiper belt objects is best explained by the presence of an unknown planet in the Solar System with a mass of 10 Earth masses in an extended orbit. At the same time, its orbit should vary from 200 to 1200 AU.

This evidence is very indirect , the probability of being in the system of a new planet from a scientific point of view is not high enough. The ninth planet has been searched for for many years, including the recent mission of WISE, in which a NASA space telescope specifically tried to spot it on the outskirts of our planetary system.

A new Kuiper belt object was discovered by a Canada-France-Hawaii telescope (at the time of construction in 1977, it was the 6th largest telescope in the world), working on a program to search for objects at the outer edges of the Solar System (Outer Solar System). ).

The OSSOS program, in particular, studies various Kuiper belt objects, in the hope of confirming or refuting the existence of a ninth planet.

The work describing the new object has not yet been published in a scientific journal and has not passed the cross-check.
