Wild predictions being made online claim a space rock up to 2.5miles wide will strike Puerto Rico.

Dates range from September 21 to the end, but most are homing in on between September 23 or 24 due to a range of Bible codes, so-called prophecies, and alleged other predictions.

However, the Blood Moon Prophecy, says the end is nigh on September 28 as that coincides with the last of four 'blood moons' (total eclipses followed with six full moons in between) over the past 18 months.

The claim appears to have its origins in a

self-proclaimed prophet Rev Efraid Rodriguez, who says he wrote to Nasa warning of the strike after receiving a message from God.

He claims he saw a vision of it "entering the airspace of the town of Arecibo in Puerto Rico, striking the sea between the island of Mona and Mayagüez and triggering a magnitude 12 earthquake.

Many "end of world" prophecies have clearly been made before and passed without incident.

Still, the latest online doomsday prophecies have been read by so many people that NASA was forced to issue a statement, that it reiterated this week, saying the chances of an impact around that time or within the next few hundred years were next to zero.

Paul Chodas, of Nasa's Near-Earth Object office at its Jet Propulsion Laboratory, Pasadena, California, said: "There is no existing evidence that an asteroid or any other celestial object is on a trajectory that will impact Earth."In fact, not a single one of the known objects has any credible chance of hitting our planet over the next century."Nasa has also published a statement on its website reassuring the global public the scare stories are not true.Mr Chodas added: "There is no scientific basis, not one shred of evidence, that an asteroid or any other celestial object will impact Earth on those dates."If there were any object large enough to do that type of destruction in September, we would have seen something of it by now.

"Nasa DOES track about 13,000 "near-Earth asteroids" but accepts this figure is only about 2% of those out there and it has no idea of the whereabouts to the remaining 98% of them.Of the 13,000 around 1,607 are classified as "potentially hazardous" meaning they are big enough and come within a few million miles of Earth - a distance considered a brush past in cosmic terms.

So are any asteroids due to pass close to us on any of these dates and what are the chances of any of them posing any danger?

An Express.co.uk investigation can exclusively reveal there are SIX so-called "close approaches" of "near Earth" asteroids due to pass within a cosmic fraction of the planet within the doommongers' seven-day predicted timescale.

Scientists predict it would take an impact from an asteroid of 1km (0.6miles) in length and upwards to actually kill off most life on the planet.

But something as small as 50 metres could destroy all of London out to the M25 boundary, and a space rock of 100metres long or more could devastate a continent, causing mass destruction and tsunamis.

How big are these six?

Of the six due to pass, those on September 23, 27 and 28, are estimated as being up to 57, 39, and 31-metres-long respectively.

In June 1908 the Tunguska asteroid exploded in the atmosphere above Siberia and is the most recent major one in world history.

It saw a 50-metre lump of extraterrestrial rock rain down, flattening around 80million trees, sending a shock wave across Russia measuring five on the Richter scale.

We found the biggest rocks set to pass are on September 22 and 24.

On the 22 two asteroids are expected to whistle past - one of up to 190 metres long - the length of eight train carriages - and another cruise ship-sized space rock of about 280 metres long.

Two days later another whopping 270metre asteroid will pass us.

How far away are they?

NASA monitors massive asteroids that pass by several million miles from Earth and smaller ones at up to about 7m miles.

It seems far, but put into context the moon is 238,800 miles from us and our closes planet is Venus at 25m miles away, so the "near Earth asteroids" pass closer to the moon than other planets, and their orbits vary.

The furthest pass of the largest three is on September 22, when the 280-metre asteroid is expected to whistle past at a relatively safe 14.7m miles from us, while the 270metre one on September 24, is a much closer 5.1m miles.

In fact, this space rock is the closest of all six objects due to pass over these days.
