Evidence seems to point to an undiscovered planet beyond the demoted planet Pluto. Caltech researchers believe there is a giant planet which orbits 20 times farther than the and takes about 20,000 years to make a full revolution. The planet is believed to be 10 times the size of Earth. Dr Konstantin Batygin and Mike Brown used mathematical modeling and simulations to make the discovery. However, no empirical evidence has been presented that shows the planet in it natural form. The news was revealed in The Astronomical Journal: Evidence For A Distant Giant Planet In The Solar System
Some astronomers believe Pluto may be a satellite or former satellite of this newly discovered planet. For centuries, cultures have speculated that a large planet existed outside of the visible Solar System. This object has been called ‘Nibiru’ or ‘Planet X.’ Ideas have circulated that ancient aliens live on this planet and visited Earth when their planet was closer to the Sun. These ideas are of course part of the human imagination and no evidence exists supporting the stories. However, this will not stop so-called ‘Ancient Astronaut Theorists’ from taking this news story and running to the wind with it.
In any event, the discover is amazing and shows how little we know of our own ‘backyard,’ the Solar System.
