Does Planet 9 Really Exist?

Caltech scientists have found certain evidence that proposed a hypothetical concept which suggests that there may be a Planet X deep in the solar system. This planet is believed to be orbiting around Sun in a highly elongated orbit. The mass of the planet is believed to be 10 times mass of the Earth and orbit about 20 times farther from the sun on average than Neptune. It may take between 10,000 and 20,000 Earth years to make one full orbit around the sun. The predicted orbit is about 20 times farther from our sun on average than Neptune (which orbits the sun at an average distance of 2.8 billion miles).

The planet is not discovered yet because it is just a hypothetical concept as it is based on mathematical modelling. Batygin and Brown nicknamed their predicted object “Planet Nine,” but the actual naming rights of an object go to the person who actually discovers it. The name used during previous hunts for the long suspected giant, undiscovered object beyond Neptune is “Planet X.”
