Have Scientists Found Planet X?

This might be big. Really big. Not the planet itself (although it seems to be huge), but the idea that scientists may have found what's been referred to for many years as the ninth planet, or Planet X.

From Fox News:

“This would be a real ninth planet,” CalTech researcher Mike Brown, who along with his colleague Konstantin Batygin, made the discovery which they are calling Planet Nine. “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.”

It is believed to have a mass about 10 times that of Earth and orbits about 20 times farther from the Sun on average than does Neptune. As a result, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the Sun.

Take a look as Mike Brown and his colleagues explain:
