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.

    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.

    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.

    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.

    Not to diminish Constantine’s work and enthusiasm but I feel like he embodies one of the most powerful human impulses; to seek out and explore the horizon, to discover the next chaotic unknown. Whether it be a prehuman hominid ape or a 21st century physicist he has that instinct to find the next untouched shore. Whether or not there is a ninth Planet, regardless of if he finds it I’m glad there’s people like him always searching

    "Who found the kuiper belt?" 'i found the kuiper belt' "Whhhaaaatt!? Sucks to be you. Others get to name their discoveries like a floating rock. You found a whole bunch of them and it's named after a dead guy" Some guy could just randomly predicts a 2nd belt and then get it named after him before ever being found. *Note: works better if your name is respected in the particular field*

    *WHO INVENTED THE SPACE ENTERPRISE?* It was the Judaeo-Freemasonry Vatican (Jesuits) instituted Heliocentricism (a corporation that has fooled billions of people) as the next centuries ticked by these science fiction stories began entering the major Universities (all faith based); from this point on the people were taught to replace Faith with Theory (pretend). ... 1543 - Jesuits invent Theory Heliocentricism 1582 - Jesuits invent Heliocentric calendar (Pope Gregorian calendar) 1651 - Jesuits invent Moon features (Selenography) 1763 - Jesuits invent Theory Atomic Energy 1809 - Jesuits invent Theory Transmutation of Species (see Theory of Evolution) 1923 - Jesuits invent Theory Missing Link (bones lost molds prove find) 1931 - Jesuits invent Theory Big Bang (another ejaculation into the virgin source) ... Lets recap Judaeo-Freemasonry sell two (2) products: 1. HEAVEN, this Faith based religion called Christianity 2. SPACE, this Theory based religion called Heliocentricism ... *Question: What year did Religion (faith) allow Science (theory) to take over the Space ENTERPRISE?* i58 . servimg . com/u/f58/19/39/28/69/blue_m11 . jpg (remove spaces)
