What if Planet X Was Actually Real?
Over the past century, astronomers have speculated about the existence of a mysterious 9th planet lurking in the outer reaches of our Solar System.
Although we've never directly observed the elusive Planet X, researchers keep finding more strange phenomena that seem to support its existence. Scientists believe that Planet X, also referred to as Planet 9, is about 17 times bigger than Earth, and made entirely out of gas.
