Does Planet 9 Exist?

  • Published on Sep 13, 2019
  • 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.

    so all in all, to bad if we find "David Bowie" in the future and it turns the solar system into a slurry mess of ejected planets and pole flipping chaos.

    I must say the guy opposing this theory (donno what to call it its not opposing hes just saying its un likely) looks more proffesional and has been a scientest for at least 25 years while the guy proposing the thery looks much less proffesional lol altho if one of them was wearing a lab coat id beleve them lol

    So finding the Kuiper Belt was difficult?
    No it was super easy, barely an inconvenience.

    guy on the video > 10k yrs rotation period
    my thought > ain't that strangely coincidental with some (still more or less hypothetical) disasters in the past, like Storegga Slide, extremely warm period of Middle Holocene (warmer than today), or drying of Africa?

    Don't wanna draw any conclusions or so, just occurred to me when he spelled out that number.

    Flat Earth has debunked all this nonsense. Space is fake. Earth was form in water and out of the water just like the bible says in 2 Peter 3V5 no big Bang Read Genesis again which is what Peter is talking about. Just liars from Nasa. The blue above us is water held back by the firmament.

    These guys are just telling stories. Space is fake. We would not have atmosphere pressure without a container. The air we breathe would escape into the ever expanding vacuum. Wake up people it's all just sci-fi. Nobody is going out into space. Any Christians on here, need to turn away from these lies and read their Bible's.

    I think planet9 or planetx is nothing but a Blackhole lurking ouside the oort cloud. Bad idea.

    Yep, it's called Pluto. Now planet 10 we are still looking for, but the math looks promising.

    You would think that using a computer model of orbiting planets with planet pushing all the other planets to the opposite side of its orbit would give them a clue of where it could be orbiting ... I mean you have a computer model showing you exactly what you can expect ...

    two additional dwarf planets orbit past past Pluto. One is bigger then Pluto. So if Pluto becomes a planet again. we will be looking for planet 11.

    I get it, I am in the old school camp regarding Pluto being called a planet.
    What you are looking for is what I called Planet X (X=10) back in the ‘80’s.

    What if the entire gravity of all objects in our solar system is being affected by Planet 9 kinda like the intermediate moment of inertia video. The solar system is moving forward in space on its greatest moment of inertia, and Planet 9 sometimes flips the orbits of Kuiper belt objects.
