The alleged planet is Nibiru (Planet X) and it is supposed to be close enough to earth this weekend so that the gravitational forces will force the earth to get out of whack and will bring hellfire and brimstone. It ought to be a spectacular sight. Oh. It was supposed to have happened September 23 but didn't. Dr. David Morrison, NASA scientists, says Nibiru doesn't exist. Why numerologists et al think it does is a mystery.
