German schoolboy, 13, corrects Nasas asteroid collision figures
Berlin: A 13-year-old German schoolboy corrected Nasa's estimates on the chances of an asteroid colliding with Earth, a German newspaper reported on Tuesday, after spotting that the boffins had miscalculated. Nico Marquardt used telescopic findings from the Institute of Astrophysics in Potsdam (AIP) to calculate that there was a 1 in 450 chance that the Apophis asteroid will collide with Earth, the Potsdamer Neuerster Nachrichten said.
