NASA has busted the world's scariest rumour confirming there is no asteroid heading towards Earth which would end humankind.

The space experts released a formal statement in response to several blog and social media posts claiming an asteroid will impact Earth sometime between September 15 and 28.

The rumours state the impact will be near Puerto Rico causing wanton destruction to the Atlantic and Gulf coasts of the United States and Mexico, as well as Central and South America.

But according to NASA, it is all untrue.

"There is no scientific basis — not one shred of evidence — that an asteroid or any other celestial object will impact Earth on those dates," NASA's Near-Earth Object office manager Paul Chodas said.

NASA's Near-Earth Object Observations Program says there have been no asteroids or comets observed that would impact Earth anytime in the foreseeable future, the statement reads.

It goes on to say all known Potentially Hazardous Asteroids have less than a 0.01 per cent chance of impacting Earth in the next 100 years.

"If there were any object large enough to do that type of destruction in September, we would have seen something of it by now," Mr Chodas said.
