The Solar System s 9th Planet

Hey guys, and welcome back to another episode of Everything Science! On today’s episode, we're discussing what scientists think might be a hidden ninth planet, hiding at the edge of our solar system.

Ever since Pluto's demotion in 2006 our solar system has had a nice, even number of planets. Four rocky bodies and four gaseous ones. Nice and balanced, right? Well, using the same mathematical models that first predicted Neptune before it was ever observed, scientists think they've found a ninth planet hiding on the far reaches of our solar system. So who knows, maybe we'll be back to nine planets before you know it.
