- TL;DR Summary
- On the basis of the orientation of the (KBOs) in kuiper belt orbit in one orientation instead of having random orientation this point enforces that that must exist a planet in the ot scurt of solar system which gravitational field forced the KBOs in one orientation
Could the existence of the 9th planet of the solar system is possible under these arguments of existence of it some where in the out scurt of solar system?
The evidence for Planet 9 comes from its gravitational pull on other bodies. If the planet exists, its gravity will affect the orbits of other planets. So if something seems to be tugging on a planet, just do a bit of math to find the source. This is how Neptune was discovered, when John Couch Adams and Urbain Le Verrier noticed independently that Uranus seemed to be tugged by an unseen planet.
In the case of Planet 9, we don’t have any gravitational effect on a planet.
What we do see is an odd clustering of small icy bodies in the outer solar system known as Kuiper belt objects (KBOs). If there were no planet beyond the Kuiper belt, you would expect the orbits of KBOs to be randomly oriented within the orbital plane of the solar system. But instead, we see lots of KBO orbits are clustered in the same orientation. It’s possible that this is just due to random chance, but that isn’t likely.
Back in 2016, the authors looked at the statistical distribution of KBOs and concluded the clustering was caused by an undetected outer planet. Based on their calculations, this world has a mass of 5 Earths and is about 10 times more distant from the Sun than Neptune. The paper even calculated a broad region of the sky where the planet might be. But searches turned up nothing. This led some to conclude the planet doesn’t exist. Orbital oddness doesn’t prove a planet exists. Just ask Planet Vulcan. Others went so far as to argue Planet 9 does exist, but we can’t see it because it’s a primordial black hole.
