A new planet in our solar system ?

Hey Charlie ! Could a new planet exist in our solar system ?

 In January 2015, Caltech astronomers Konstantin Batygin and Mike Brown have found mathematical evidence and computer simulations suggesting there may be a ninth planet in the solar system right behind Neptune. They have called it « planet nine ». Since « planet nine» so far has not yet been observed directly, its existence stays only theoretical at this point. From 2006 on, school all over the world has taught that the solar system contained 8 planets. But it may have been 9 planets all along.

The hypothetical planet is believed to have 10 times the mass of Earth and about 4 times Earth's diameter. Moreover, Planet nine is estimated to have a very long orbit that take between 10,000 to 20,000 years to orbit the sun.

Evidence continues to mount for its existence through its gravitional effects. There are three separate reasons that proves its existence.The existence of a large object could explain the unique orbits of at least five smaller objects discovered in the distant Kuiper Belt. The Kuiper Belt is a vast region of primordial debris in the outer Solar System, extending from the orbit of Neptune. All five objects have elliptical orbits that go in the same direction. Normally, the orbits should be all over the place. The second point shows that Planet Nine's influence might have tilted the entire solar system except the sun. These two reasons on their own proves that all of this is influence by a large gravitational source. The third explanation comes from the computer simulations predecting that more objects in the solar system should be titled out of the plane.

This is not the first time that a planet in our system solar is discovered theoritically. Deviations in the orbit of Uranus has been observed. Neptune was pridicted to exist before it was actually discovered using similiar mathematical modeles back in 1846.
