A 13-year-old German schoolboy corrected NASA's estimates on the chances of an asteroid colliding with Earth, a German newspaper reported, after spotting the boffins had miscalculated.
Nico Marquardt used telescopic findings from the Institute of Astrophysics in Potsdam (AIP) to calculate that there was a
one in 50 chance that the Apophis asteroid will collide with Earth, the Potsdamer Neuerster Nachrichten reported.
NASA had previously estimated the chances at only one in 45,000 but told its sister organisation, the European Space Agency (ESA), that the young whizzkid had got it right.
The schoolboy took into consideration the risk of Apophis running into one or more of the 40,000 satellites orbiting Earth during its path close to the planet on April 13, 2029.
Those satellites travel at 3.07 kilometres a second, at up to 35,880 kilometres above earth - and the Apophis asteroid will pass by earth at a distance of 32,500 kilometres.
If the asteroid strikes a satellite in 2029, that will change its trajectory making it hit Earth on its next orbit in 2036.
Of course if it does it's the end of life as we know it.
