We have possibly regained a 9th planet! - EDIT

"We have convincing evidence that the census of the solar system is incomplete."

Okay okay; so before I go on this topic, and before I get tomatoes thrown at me, please please let me just say one word, okay?

This planet hasn't been discovered... YET! 

HOWEVER, there is a GOOD chance that we have another planet in our solar system based on proper, correct evidence.

I invite you to go check out the video from this article:

This latter video clearly explains how they discovered it:

English





French




The article I mentioned above explains that the planet would actually originally have been closer to the sun when it first formed, just like the other planets, but was pushed back by the gravitational force of the other planets.
