As recently as last Friday astronomers were concerned that the next encounter might be too close for comfort. A panel convened by the International Astronomical Union (IAU) announced on Nov. 3rd that 2000 SG344 might hit Earth in the year 2030. The chances of an impact were slim, they said, and new data to refine the object's orbit would likely rule out a collision altogether.
That's exactly what happened. Shortly after the IAU announcement, astronomer Carl Hergenrother found "pre-discovery" images of 2000 SG344 from May 1999 in archives from the Catalina Sky Survey.
"The pre-discovery images let us calculate a better orbit that absolutely rules out a collision in 2030," says Donald Yeomans, manager of NASA's Near Earth Object program at the Jet Propulsion Laboratory. "It won't come any closer to Earth than 11 lunar distances. However," he added, "the new orbit increases the chances of encounters in years after that. For example, there is a 1-in-1000 chance of a collision on Sept. 16, 2071."
