The race is on to catch the first glimpse of Planet Nine—and no, it’s not Pluto

Forget Pluto—researchers at Caltech have found evidence of a ninth planet in our solar system that might be about 10 times as massive as the Earth.

They haven’t actually observed the planet, but as you can see in the video above, there are good reasons to believe it exists, and the researchers are confident that many telescopes already have the capacity to confirm it.
