"Aernus", A proposed new planet in the Kuiper Belt Options

[ustrax]

Tomorrow at DPS Patryk Lykawka will make a presentation where he points out to the existence of a planet with the diameter of the Earth at 100AU.

I received his answers regarding the work done yesterday, here's some of it (the rest is you know where...):

"This massive planetesimal would be, now, at this moment in the history of the Solar System, orbiting the Sun at a distance of, at least, 100 AU, or, simplifying, 3 to 4 times more distant from our star than Pluto.
A far, massive, transplutonian planet in the Lykawka’s description who remarks the importance that the orbital evolution of this planet may be the key to answer several unexplained enigmas of the Kuiper Belt, among which he points out a few…:
The excitation actually observed in the region between 40 and 50 AU is one, another are the populations of different types of objects in the Belt and their orbital characteristics.
Another two pieces of the puzzle can also be put into place under Patrik work: the Belt’s truncated region in the 48 AU region and its small total mass."

What's your opinion regarding this?...
According to him this is not like Planet X, his study even erases Planet X from the map...

EDITED: "Aernus" is the name I'm using, it was the divinity of the Zoelae, a pre-historic tribe that lived in the most remote corner of my country...
