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?

Huge thanks to:
Prof. Konstantin Batygin, Caltech
Prof. David Jewitt, UCLA

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.

Their theoretical model of Planet Nine is remarkable, a lot of deep thinking was put into it obviously. In any event, I think it exists and its discovery will bring about a reawakening in astronomy whereby more people will want to become more cosmic literate about the universe.

It sounds to me like no one knows if it exists, no one has a strong feeling it doesn't, but they have to opposing views, one tries to prove it doesn't while another tries to prove it does, science has always been this way and it's what helps it progress.. never shoot someone down until you can prove they are wrong

How do you then explain the Oort Cloud? Those bodies do not follow any plane according to the Theories I have seen. Many thousands of objects out there too faint to be seen. It is so true that we know sp little about our own Solar System but much more about around other stars.

Tbh they downgraded Pluto thinking it was just a rockbor astriod caught by our solar sytem. Only to find 4 years later, with the Voyager probe flyby that it has an atmosphere and more moons. Just that fact Pluto should be the 9th planet again and no doubt there is a 10th planet as comets give indicators of objects being pulled into our suns gravity.
Pavel
Pavel 6 日 前
​@Kln Wg Good point! It would be probably a dwarf planet according to the current definition, but it would be funny if it was a large object with multiple Earth masses. I don't know if you noticed, but in astronomy, there are so many confusing concepts due to historical reasons, for instance, Sun in classified as a yellow dwarf star despite being bigger than some 80% of the stars in the universe ;)

@Pavel then by that definition the theorectical 9th planet would not of cleared its own orbit of debris.

No, then we would have hundreds of planets. Pluto has not cleared its orbit from the other large objects, which is part of planet definition.

No, that's not possible. Planets can and do orbit far away around two closely bound stars, but a planet's orbit will always be circular (or ellipcital, but never an 8 shape).

its actually more possible that we have a second sun that is dead its just mass so as i swing round it drags our sun forward it also pulls the planets with it and sometimes steals some, the math speaks for its self.
Релёкс84
Релёкс84 28 日 前
The math does not say that. You're just speaking without any actual understanding.
Noone From Nowhere
there are at least 12 planets, the orbital pull of all the plants prove as such, none of them are stable, its also why our moon gets further away every year and closer on its inner orbit, and will eventually hit or get dragged out into space and join or hit another planet, the flat plane our planets orbit on will not always be so, and we are now on the outward position of the orbit flow, they will start spreading untill they settle into a new orbit state, of wich we will not be alive to see.

What if the kuiper belt is planet nine deconstructed? I guess it would depend on the combined gravitational force of each object in the belt. Not to mention it's connection to the Oort cloud.
