My problem with Planet X is If it is coming into orbit wouldnt we have seen it by now?
This theory is not suggesting a Planet X in the doomsday sense, but is more an implication that there may still be another undiscovered planet drifting around the kuiper belt. While I accept this is a remote possibility, I do not accept that every so often it swings its way into the inner solar system causing mayhem and havoc before disappearing to the outer reaches of the solar system for another millennia.
