The bad news is there is a one in three chance for an impact that would cause local damage in the next 100 years, said Richard Binzel of the Massachusetts Institute of Technology.

Binzel recently created a 10-point scale for estimating the threat of a near-Earth asteroid, with zero indicating no chance of an Earth impact and 10 indicating a certain Earth impact with severe, global damage.

"Dawn's crowning success at Vesta was the delivery of instruments that require proximity, exemplified by the gamma-ray and neutron measurements of Prettyman et al. yielding elemental abundances that unequivocally confirm the meteorite links, " Binzel wrote.
