Moontanman Posted February 4, 2009 Report Share Posted February 4, 2009 Asteroid bound for Earth! Warn your grandchildren 04 February 2009 by David Shiga AN ASTEROID that had initially been deemed harmless has turned out to have a slim chance of hitting Earth in 160 years. While that might seem a distant threat, there's far less time available to deflect it off course. Asteroid 1999 RQ36 was discovered a decade ago, but it was not considered particularly worrisome since it has no chance of striking Earth in the next 100 years - the time frame astronomers routinely use to assess potential threats.
