NASA denies the existence of Nibiru or Planet X

Another theory that gained internet traction is the Nibiru theory.

It predicted the end of the world on 23 September 2017.

Nibiru refers to a Planet X, or Nibiru, means to a fictitious planet claimed to crash into Earth.

Nibiru was first heard of in 1995 by Nancy Lieder who claimed to be a medium between aliens from Zeta Reticuli star system and Earth.

If Christian numerologists are to be believed, the world will end on 23 September.

David Meade, a Christian conspiracy theorist has made this prediction about Doomsday citing verses Luke 21.25 to 26 from the Bible.

He said the "recent solar eclipse and Hurricane Harvey, are signs of the apocalypse".

He said a Planet X will collide with the Earth leading to the world's end.

NASA addressed the issue and said that all predictions about the world ending on 23 September 2017 were false.

NASA said, "Nibiru, doesn't exist, so there will be no collision".

Further, the agency said if this had any truth then the astronomers would be tracking it since decades.

Moreover, NASA contended it would've been visible to the naked eye by now.
