NASA scientists have announced that new observations of 2011 AG5 show that this asteroid, once thought to have a worrisome potential to threaten Earth, no longer poses a significant risk of impact. The orbital uncertainties of the 140m diameter near-Earth asteroid had previously allowed a 0.2% chance of collision in Feb. 2040, leading to a call for more observations to better constrain the asteroid's future course.
Answering the call, University of Hawaii astronomers Dave Tholen, Richard Wainscoat and Marco Micheli used the Gemini 8-meter telescope at Mauna Kea, Hawaii to successfully recover and observe the small and very faint asteroid on October 20, 21 and 27, 2012. After extensive astrometric analysis by the team in Hawaii, all observations were then sent to the International Astronomical Union's Minor Planet Center in Cambridge, Massachusetts.
An analysis of the new data conducted by NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California, shows that the risk of collision in 2040 has been eliminated.

Wait...Are you even talking about 'Apophis'?

While it is true that they asked for help tracking this trajectory, they only did so because the threat was far enough out that if it WAS on a collision course they could possibly do something about it. I GUARANTEE you that if someone at NASA discovered an imminent threat that was say a week out and was an ELE we would not hear about it.
The amount of craziness that would ensue would be off the charts.
