Astronomers Discover Planet X,Solar System Has 9th Planet

 

Scientists say they finally have 'solid evidence' for Planet X, a true ninth planet on the fringes of our solar system.

The gas giant is thought to be almost as big as Neptune and orbiting billions of miles beyond Neptune's path - distant enough to take 10,000 to 20,000 years to circle the sun. 

This Planet 9, as the two Caltech researchers call it, hasn't been spotted yet

Researchers inferred Planet X's presence from the peculiar clustering of six previously known objects that orbit beyond Neptune. 

They say there's only a 0.007% chance, or about one in 15,000, that the clustering could be a coincidence. 

Instead, they say, a planet with the mass of 10 Earths has shepherded the six objects into their strange elliptical orbits, tilted out of the plane of the solar system.
