A MYTHICAL planetary system will pass the Earth in 2018, causing seismic chaos on our planet due to its gravitational force, is is alarmingly being claimed.
End of world prophets, who believe in the growing Nibiru/Planet X theory, are convinced it is a mini solar system consisting of a sun, planets and moons, which is lurking on the edge of our solar system.
They claim it has a huge orbit of the sun.
Nibiru believers are convinced the "rogue system" is making its way from the outer solar system inwards, where it will wreak havoc on Earth as it passes at about four million miles away.
They say the planet will cause the poles to switch, sparking great earthquakes and volcanic eruptions, which threaten billions of lives.
Nibiru believer David Meade claims humanity could witness naked-eye sightings of Planet X “early this year”.
So much so, the Christian fundamentalist and conspiracy theorist is now preparing for the so-called apocalypse, by going into hiding.
He said: “The events of the next several months are so major that as they say in the Intel community, I’m going ‘in the dark’.
“The events are so huge and are both supernatural and major natural cataclysms that I wish to leave it at that.
“It’s a surprise ending. It has nothing to do with politics, nor with man, actually.
“It's predetermined and about to transpire. It's straight out of the Book of Revelation.”
However, it is some consolation that Mr Meade predicted Nibiru would become visible in the skies from September 23.
He then said it would pass us in October and December.
Other online doomsayers continue to claim Planet X will soon appear – and may even already be in our skies.
Christian conspiracy theorist Paul Begley said: “There are asteroids, meteors – it’s all happening. The heavens are being shaken by some type of force, a gravitational pull.
“People are spotting now what looks like potentially Planet X.
“I have from one night three different people send me pictures pictures of what looks like a Planet X.”
He also pointed to a Bible passage from Luke 21: 25
It reads: “There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea.”
However, the truth is likely to be very different.
The likes of Mr Meade and Mr Begley have been predicting for years of an awful apocalypse that has never materialised.
And it may be that Mr Meade has gone into hiding from critics of his book Planet X - The 2017 Arrival which famously warned Nibiru would pass and trigger the rapture at the back end of last year.
Cynics say doom-mongers pedal these myths in order to cash in from advertising revenue on YouTube or from book sales.
Mathematician Robert Walker, who has been fascinated by space and astronomy since the 1960s, criticised YouTube doom prophets on the Quora debate website.
He wrote: "Some are just out and out frauds doing it for the YouTube ad revenue (which can be a lot, thousands of dollars a month for the most popular Nibiru channels, according to the estimates of SocialBlade), or who knows what reason.
He even launched a petition asking YouTube to stop adverts on such videos.
He said: "This is to remove the profit motive for predicting the end of the world on YouTube.
"I think it is unethical to reward people with ad revenue for predicting the world will end in click bait titles."
After the incorrect predictions in the 2017 book, Mr Meade is now promoting a new book Planet X and Beyond - The End of Days.
NASA points out that Nibiru is a myth and a hoax, despite the amount of believers.
NASA scientist Dr David Morrison 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 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."
Space boffin Dr Brian Cox has also insisted Planet X does not exist.
And associate Professor Jonti Horner, an astronomer at the University of Southern Queensland in Australia, said: "I’ve never heard of anybody who’s an actual astronomer talk about Nibiru before.
"It’s basically an urban myth — it’s like having a biologist coming out and talking about werewolves and the Sasquatch being real. You just wouldn’t hear it.”
Express.co.uk asked Mr Meade if it was time to accept Nibiru does not exist, and his book was wrong, but he has yet to respond.
