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.

    I immediately recognized Konstantin from the planetary series on NOVA.

    So are all of these properties not just caused by the rotation of the supermassive blackhole at the center of our Milky Way Galaxy? To me it seems like our system's orbit around the center of our galaxy is what is affecting the orbits of the bodies of our solar system. This creates a trail of celestial bodies around the sun as it itself orbits the Milky Way center. That's just what it seems like to me, a layman. Does anyone know if the biased orbital direction is the tangent of the orbit of our sun around the galaxy?

    Who is the moron who cannot count? Pluto was repromoted back to full planet status a couple years ago and there is in addition 5 objects allocated to the planetoid status that Pluto was temporary allocated. Any way you cut it any additional planets is beyond 9 so kind of a major goof asking about "Planet 9"

  • ONE (Eileen Colts)

    Yes. It's called Planet 10, Planet X or Nibiru. Pluto will always be the 9th Planet whether officially recognized or not.

    What about Hubble? A telescope that's able to see light years away, and we are so curious to wonder if there is a 9th planet.

    I'm curious, if Planet 9 does exist and if it does orbit close enough to the sun, how would it affect the oceans of the Earth? Is there a correlation with such an orbit with the dating of ice ages on this planet?

    Yes planet does exist. It has existed for a very long time. We have known about it since. 1930 when it was discovered. It is called PLUTO. If this is true then it would be the 10th planet.

    Would a 5EM planet have enough gravity to flip orbits and change orbits that much?

    • Vishal Bondwal
      Vishal Bondwal 2 days ago

      It seems to be doing it to smaller Kuiper belt objects, not to heavy masses. Given that Neptune could be discovered based on disturbances in Uranus' orbit, I guess it's not that unlikely that a 5EM planet would fling about comets and asteroids.

    Did anyone else hear that subtle background music? I kept thinking that a neighbor was playing something, but it cut out every time I paused the video. Way too faint to really make out, but something was definitely there in the audio.

  • Ethan Lloyd

    Love this style of video, but, the pro-argument kinda threw me off. Specifically, when asked about "What about the 10k time period?" He says "Now, lets ignore the period and focus on the mass, this 5.x times Earth mass, is actually really common." Entirely ignoring the question. A lot of the stuff he's talking about is very buzz-wordy. Would be cool to see some cited relevant sources for both sides.

    The right time to talk about planet 9 as if it exists at all, would be right after you know for sure that it exists. The same goes for everything else in science. Unless you're a climate change believer of course. In that case you just hold a young girl in front of you as a human shield until everyone shuts up and believes you :)

    if the explanation of asteroid belt formation was the gravitational force of Jupiter...vice versa there should be explanation of kuiper belt formation with another giant plant gravitational force which should be more than 5times mass of earth...theoretically...

    The sky observations in the last 200 years is comparable to a shutter opening and closing in half a second - the image captured is only a microcosm of what may be happening over 20000 years.

    Sumerian draw our solar system billion years ago in the way just like we know them, same size same place same planet's that we know just one extra planet everyone is coping from them they describe Uranus, and finally! we can see a photo of it and o my god it's just like how Assyrians,babilyonians, Sumerians describe it does exsit but it's far a way I'm Assyrian btw

    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

    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.
