Last year Nasa detected an object, that could be a comet or an asteroid, on a path towards Earth.
The space agency has said the mysterious object will safely pass Earth at a distance of nearly 32 million miles (51 million kilometres) on February 25th.
But one self-proclaimed astronomer has come up with an alternative theory, suggesting the asteroid will crash into Earth on February 16th and trigger a mega-tsunami, according to reports.
The strange object, named 2016 WF9, was discovered last year.
Over the course of 4.9 Earth-years, it has travelled inward, passing under the main asteroid belt and the orbit of Mars until it will swing just inside Earth’s own orbit.
The object, which is a blurred line between an asteroid and a comet, was discovered by Nasa’s NEOWISE mission.
Self-proclaimed Russian astronomer Dr Dyomin Damir Zakharovich said it is heading straight towards our planet.
‘The object they call WF9 left the Nibiru system in October when Nibiru began spinning counter clockwise around the sun,’ he said.
‘Since then, Nasa has known it will hit Earth. But they are only telling people now.’
If the asteroid hit Earth, he says, it could destroy cities or cause a tsunami. ‘We are all in peril.’
Nasa does not think the object will hit Earth, instead it is saying it will pass nearly 32 million miles (51 million kilometres) away from the planet.
