Does Planet 9 Exist?

A planet has been predicted to orbit the sun with a period of 10,000 years, a mass 5x that of Earth on a highly elliptical and inclined orbit. What evidence supports the existence of such a strange object at the edge of our solar system?

I had heard about Planet 9 for a long time but I wondered what sort of evidence could support the bold claim: a planet at the very limits of our ability to detect one, so far out that its period is over 60 times that of Neptune. The planet 9 hypothesis helps explain clustering of orbits of distant Kuiper belt objects. It also explains how some of these objects have highly inclined orbits - up to 90 degrees relative to the plane of the solar system. Some are orbiting in reverse. Plus their orbits are removed from the orbit of Neptune, the logical option for a body that could have ejected them out so far. The fact that the perihelion is so far out suggests another source of gravity was essential for their peculiar orbits.

    I've been wondering if the 10,000 year orbit of planet nine would have the type of impact on the earth's climate and electromagnetic polity hypothesized by Graham Hancock and the Younger Dryas event from roughly 12,600 years ago. Perhaps nearly all of humanity is destroyed and re-built based on the cycle of planet nine. As it nears earth, or perhaps is the furthest point away, is causes these mass extinction events.

But have you ever heard of the name "Nibiru"? Because alongside "Planet 9" and "Planet X", "Nibiru" seem one of those popular names for this object. Besides, I feel like it would sound both better and make more sense than "David Bowie" XD

    So, the three criteria of the IAU for a full-sized planet are: 1) It is in orbit around the Sun. 2) It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape). 3) It has “cleared the neighborhood” around its orbit. Pluto got disqualified for not 'clearing the neighborhood' as it spends @90% of it's orbit in the Kuiper Belt. For 20 yr segments it is not in the Kuiper Belt, and is actually closer to the sun than Neptune, so thus is in a clear neighborhood. Ceres was disqualified for being in the Asteroid Belt, same reason, not a clear neighborhood. If the Kuiper Belt disqualified Pluto, then how would Planet 9 (Planet X) not be disqualified for the same requirement? If there is a Planet 9 (X) in the Kuiper Belt wouldn't it too fail Criteria 3? Beyond the Kuiper Belt is the Oort Cloud, a 3 dimensional cloud of debris. How would anything in the Oort Cloud be capable of “clearing the neighborhood” around its orbit? This is assuming the Oort cloud is considered within the Sun's Heliosphere, which is not certain. Some models have the area between the Kuiper Belt and the Oort Cloud as interstellar space. Not sure you could define an entity beyond a star's heliosphere and in interstellar space as a planet. Simple logic and the IAU definition disqualify almost any chance that there is a Planet 9 (X) What if that is a black hole, massive dark matter formation (MACHO) or a wormhole?
