Nibiru is a hypothetical planet supposedly lurking somewhere in our solar system. While NASA says that it does not exist, conspiracy theorists insisted that it was real and would slam into the Earth in the year 2012.
For the record, Nibiru is also called Planet X and should not be confused with the hypothetical Planet Nine that is also called Planet X. We will get to Planet Nine shortly.
Nibiru was first proposed by Zecharia Sitchin in his 1976 book, The Twelfth Planet, where he claimed that it orbited the Sun every 3,600 years. Many years later, self-proclaimed psychic Nancy Lieder declared that aliens had warned her that Nibiru would slam into the Earth in 2003. Later, she changed the date to 2012.
In 2011, Comet Elenin passed by Earth and broke apart after flying too close to the Sun. Hard-liners insisted that the comet was planet Nibiru on its approach to crash into Earth. The fact that we are reading this article means that planet Nibiru probably doesn’t exist. Or it just missed Earth and will be returning in 3,600 years.
