There's no chance to be a black hole. If it was, earth and rest of the whole system could be somewhere in the deep space. There is a theory that says, even if a small black hole pass nearby the solar system, all the planets will move pretty far from its current position and it'll be catastrophic. So, I guess there's no black hole. Actually, I think astronomers hide the truth about this 9th planet.
Why hide the truth? What would be gained by this?
