Whether you call it Planet X, Nibiru, a comet or a star, the forthcoming disturbance in the solar system is still hotly contested.
NASA claims, “Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist.”
