The monster 270-metre space rock called 2012 TT5 is one of four "near-earth" flybys between now and September 28 when online doomsday prophets claim the world could end

Wild predictions being made online claim a huge space rock will strike Puerto Rico.

Dates ranged from yesterday, September 22, to the end of the month, due to a range of Bible codes, so-called prophecies, and alleged other predictions.
NASA gives each asteroid a "condition code" from zero to nine of how certain it is about its predicted orbital path.

A zero means there is "good certainty" about it, while nine means it is highly uncertain, with numbers in between on a sliding scale.

The cruise-ship-sized rock 2012 TT5 scored six, meaning there is quite high uncertainty about its position.

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.

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 tracks 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.
