Where a new planet might be found within our solar system

I don't think there's going to be a new planet

A new planet might be found outside the territory of solar system.

Explanation:

The new planet of the solar system, the hypothetical Planet Nine is found to be in the outer territory of our solar system. It is considered as the clustered orbit of collective extreme Trans Neptunium bodies or eTNOs. It is five-ten times bigger than the Earth and its orbit is 800 times elongated.

There are many propositions regarding the discovery of the planet, one of which is proposed by Konstantin Butyrin and Michael Brown that says that planet nine can be the part of a gigantic planet. However, there is no clear evidence regarding the existence of this planet till now.
