Nibiru is said to orbit the Sun every 3,600 years on a journey, which takes it beyond the fringes of the solar system. No official observations of the planet, sometimes dubbed Planet X or Wormwood, have ever been made but conspiracy theorists believe it is real. Nibiru’s passage through the solar system is said to herald the apocalypse and destruction of civilisation. The planet, which is believed to be 10 times the size of Earth, will supposedly crush our home world with its gravitational waves, triggering earthquakes, volcanoes and tsunamis.
And if these bizarre pictures taken over the US state of Wyoming are to be believed, then the doomsday planet may have already arrived over Earth.
Joshua Weickum of Casper, Wyoming, claims to have taken pictures of Nibiru high in the sky on a bright sunny day.
Mr Weickum told Express.co.uk he saw a “blue planet-like” object after snapping some photos of clouds.
He was adamant the supposed Nibiru sighting was not a lens flare on his camera but the real deal.
The eyewitness said he took a second photo of the blue orb after it disappeared behind cloud cover.
Mr Weickum said: “I personally took these photos last week and I don’t think they are lens sprites.
“The blue planet-like dot appears to be visible behind clouds in a second photo taken moments later after I took a few steps forward to get some cloud pictures.
“I didn’t notice any of it at the time, I just saw some clouds I randomly decided to pull over and photograph.
“A near-perfect circle seems to be visible in the same spot the planet was before clouds obstructed the view. I’ll let you decide.”
The Nibiru theory first emerged in 1976 thanks to the work of language scholar Zecharia Sitchin, who believed the planet was venerated by the ancient Sumerians.
Nibiru was dubbed the 12th planet and ancient Babylonian texts are said to describe its lengthy orbit of the Sun.
Many conspiracy theorists believe the mystery Planet X is inhabited by a technologically advanced race of aliens known as the Annunaki.
There is, however, no scientific evidence to support the claim Nibiru or any other doomsday planets are real.
According to US space agency NASA, all claims of Nibiru being real are a hoax.
NASA wrote on its website: “The planet in question, Nibiru, doesn’t exist, so there will be no collision.
“The story of Nibiru has been around for years (as has the ‘days of darkness’ tale) and is periodically recycled into new apocalyptic fables.”
And NASA’s scientist Dr David Morrison also said: “There is no credible evidence whatever for the existence of Nibiru.
“There are no pictures, no tracking, no astronomical observations.
“I can quite specifically say how we know Planet X or Nibiru does not exist and does not threaten the Earth.
“Firstly, if there was a planet headed into the inner solar system that was going to come close to the Earth, it would already be inside the orbit of Mars, it would be bright, it would be easily visible to the naked eye – if it was up there it would be easy to see it, all of us could see it.”
