A series of articles on the public policy debate surrounding asteroid 1997XF11. A March 11 report predicted that this asteroid was likely to collide with the Earth in 2028. However, within a few days, archived data was used to show that the prediction was wrong and that the asteroid was actually going to miss the planet. The debate that has followed this incident has tried to understand what led to the false alarm and how it could be prevented in the future. The fear is that a more dire false alarm could cause unneeded social unrest and panic. The main proponent of a policy has been Richard Binzel, from MIT. He argues for a 'hazard-index' similar to what is used for earthquakes that would give a quantitative assessment of the threat.
