--the deal is, there's no legitimate confirmation of any of this from any accredited astronomical sources. Not even a hint of a huge planet sized body heading our way. And it would have to be that big to have a gravitational effect that is more severe than the lunar pull. It would have to be quite large, plus pass by quite close.
Not sayin' that it is there or not, just that I have yet to read a source that is anything but second hand or third hand hearsay.
If it does happen, well..interesting times. We are only at 600 feet here...
