Scientists Make Huge Discovery About Our Solar System


Scientists believe they’ve found evidence of a ninth planet in our solar system.

Two astronomers reported that all signs pointed towards the discovery of a ninth planet -- as the objected discovered more accurately fits the description of a planet than Pluto did.

“We are pretty sure there’s one out there,” California Institute of Technology professor Michael E. Brown told The New York Times.

Brown and his CalTech colleague, Konstantin Batygin, examined the motion of a cluster of small objects in the solar system and determined that they were being influenced by an unseen body.

“There is no planet found. It's all circumstantial evidence,” Carnegie Institute of Science astronomer Scott Sheppard said of the planet, which has yet to actually be seen. 

“It's like we're at a crime scene looking at the blood on the wall, and we're trying to explain how the person died."

Named Planet Nine, the object has a mass of about of 10 times Earth’s mass and orbits roughly 20 times farther from the sun than Neptune does. Brown said it would take Planet Nine up to 20,000 years to orbit the sun.

“This would be a real ninth planet,” he said, reported USA Today. “There have only been two true planets discovered since ancient times, and this would be a third. It's a pretty substantial chunk of our solar system that's still out there to be found, which is pretty exciting."
