spacetoday.net: NASA rules out Apophis asteroid impact in 2036

New observations of the near Earth asteroid Apophis have ruled out any chance it will hit the Earth in 2036, NASA announced Thursday. The observations in 2011 and 2012, plus those carried out when the asteroid made a relatively close approach to the Earth on Wednesday, allowed scientists to refine the asteroid's orbit. That new orbit effectively ruled out any chance that the asteroid, about 325 meters in diameter, will impact the Earth in 2036, with the odds of an impact now less than one in one million. Previously, there had been a very small chance of a 2036 impact, depending on the path the asteroid took when passing close to the Earth in April 2029.
