Planet Nine, the new planet that has been discovered inside of our solar system. Planet Nine is a planet that astronomers,Konstantin Batygin and Mike Brown, have found with research and evidence. Because they used research and evidence Planet Nine hasn't been seen but astronomers believe that they have enough evidence to prove that it is in our solar system. The evidence to prove that it is in our solar system is that scientists have recently noticed a change in orbits of space objects near by,and that can only be caused by a massive planet.This is also how astronomers discovered the planet of Neptune because they also noticed a change in gravity with the other planets .This planet is also causing a clustering of asteroids and comets in the Kuiper Belt.The astronomers used the space-based Kepler Mission Telescope to see the changes and to locate where this planet might be.There are about 2,000 identified planets that are surround our solar system but none are a big deal because there is nothing unique about them like Planet Nine.Planet Nine is different from the other 2,000 identified planets because this planet is actually in our solar system, a place we should have known a lot about by…
