There might be an undiscovered “Planet 9” in our Solar System. Scientists have been looking for another planet for years, and now we might have actually found the exact location of the planet, if it even exists. Scientists believe it exists because there seems to be a gravitational “pull” on some icy bodies in the depths of the Solar System. Neptune was discovered because it had a gravitational pull on Uranus. Scientists predict that if planet 9 exists, then it will be about 5 times bigger than Earth, and 10 times Neptune’s distance from the Sun.
