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?

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.

  • Was "Planet 9" and even others extra-solar and were considered wandering "Stars" or wondering planets from former collisions of other galaxies or even ours ? This might define the off angle. Just a thought. I don't consider all of the planets and space junk started from the junk box our star started with to create a system.

  • The old fossil that is wrong about people being psychologically misconstrued about the undiscovered planet.. there may not currently be any conclusive evidence, but until you can rule it out with 100% certainty a slim chance can become reality.. he’s the type of dunce that values his opinion over everyone’s. Also expects people to believe his word without question..

  • Long time ago there was another planet in our solar system between Mars and Jupiter. The name of that planet was Phaeton or Mallona, Mallona means broken planet. Mallona was destroyed during a nuclear war, only the four moons of Mallona survived. You will know everything about Mallona and more if you read the books of Jakob Lorber (1800 - 1864) and Leopold Engel (1858 - 1931).

  • This theory is based on the perturbations of Saturn, Uranus and Neptune from a gravitational perspective. That is some mass at some distance is causing through gravity the anomalic behavior of these Planets. What is not considered is the real reason of the perturbations in each of these bodies orbits. Saturn, Uranus and Neptune all beat to a different drummer as far as time goes.The value of a momentum of duration of a second on each body is slightly shorter than it is on Earth and each other. Time is based on the distance from the seat of the Sun plus the mass of the object it is being measured on. At our distance and mass we place a value of momentum as being one interval known as the second. It is not the same on Mercury, Venus nor Mars nor in the Asteroid Belt nor Jupiter. Based on the astronomer's calculations of Planet nine's mass, they should be able to pinpoint its location relatively easy, but they find nothing at the appropriate distance. . .

  • see, people, this is why Pluto needs to be a planet. If Pluto's planet 9, then that makes this new one Planet 10, AKA Planet X. Who doesn't want to go looking for Planet X?

And they believe it so much that, even though he's not a fascist, racist, Hitler-ish puppet of Putin, they are convinced he is. #Trump2020

  • Since when is Pluto not a planet? At what point is a midget not a person that they lose their human rights or classification

    DragonsREpicDragonsREpic8 gün önce
    • "Since when is Pluto not a planet?" Since August 2006. "At what point is a midget not a person that they lose their human rights or classification" Pluto haven't lost its classification because of its size. The new definition for "planet" that was made in 2006 is: A "planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit. Pluto fulfils (a) and (b), but not (c). So objects that only fulfils (a) and (b) are dwarf planets. BTW, with that new definition, Ceres (in the asteroid belt between Mars and Jupiter) was upgraded from "asteroid" to "dwarf planet". Ceres used to be a planet when it was discovered in 1800, but then it losts its status at about 1850 and became part of the new categroy "asteroid", when more and more objects were discovered in the asteroid belt, and it would not make sense to classify them all as "planets". So in the 1850s Ceres suffered the same fate as Pluto in 2006.

  • basicly the hypothesis is not believed by enough people to give hubble telescope a go looking over there. (as from earth the atmosphere is mostly bothersome in general looking for such a dim objectt). well it will be a long long time before we know it its there or not then

  • Writing this with the full knowledge that it may never be seen by someone with the proper knowledge: in the video, they mentioned that some of the kuiper belt objects have orbits in the same direction and that only a few have been spotted to be orbiting the other way. Does any smart person know if that direction happens to be the opposite of where the Sun is going around the galaxy? Would it make sense that most of the objects orbit in that direction because the sun keeps pushing that way in its race around the milky way and "leaves them behind"?

    • I recommend this video: Basically its just too small. The hubble telescope can capture distant galaxies because they actually appear very large in the night sky, but cannot capture good photos of pluto for instance because it appears far too small (despite being significantly closer).
