Does Planet 9 Exist?

  • Published: 13 September 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.

    Yes it does exist
    But it is hidden, under the disk.

      Yes planet 9 does exist, it's called PLUTO!

        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?

          Now ask them the real question - Is planet 9 a black hole - hint. It is.

                      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?

                                                  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.

                                                    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 :)
