(Image credit: NASA/Goddard/University of Arizona) Technically, that's a small increase in risk, but the scientists behind the new research say they aren't worried about a potential impact.

While a slightly higher risk than past estimates, it represents a minuscule change in an already minuscule risk, NASA said. Estimates produced before OSIRIS-REx arrived at the space rock tallied the cumulative probability of a Bennu impact between the years 21 at 1 in 2,700, according to NASA. As a result, scientists behind new research now say they're confident that the asteroid's total impact probability through 2300 is just 1 in 1,750. And with that incredibly detailed view of the asteroid, experts studying potential space rock impacts with Earth have been able to fine-tune their existing models of Bennu's future. The agency's OSIRIS-REx spacecraft spent more than two years closely orbiting the space rock. ![]()
