"I think that, overall, the situation has improved." Precision counts I think that, overall, the situation has improved. Bennu is a 500-meter wide asteroid that orbits our sun, following a trajectory that periodically brings it alarmingly close to planet Earth. "The impact probability went up just a little bit but it's not a significant change, the impact probability is pretty much the same," lead author Davide Farnocchia, who works at NASA's Center for Near Earth Object Studies in California, said during a news conference held Wednesday (Aug. NASA scientists have used new data and complex computer models to predict the precise path of the Bennu asteroid for the next 300 years, according to Icarus. And besides, the lessons the research offers for asteroid trajectory calculation could reduce concerns about potential impacts by other asteroids more than enough to compensate.

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. 'I think that, overall, the situation has improved.The agency's OSIRIS-REx spacecraft spent more than two years closely orbiting the space rock. 'The impact probability went up just a little bit but it's not a significant change, the impact probability is pretty much the same,' lead author Davide Farnocchia, who works at NASA's Center for Near Earth Object Studies in California, said during a news conference held Wednesday (Aug. It observed its size, shape and composition, and tracked its orbit around the sun.The spacecraft collected a sample of the. As it turns out, there’s actually a greater chance than previously thought that the asteroid will collide with Earth. Technically, that's a small increase in risk, but the scientists behind the new research say they aren't worried about a potential impact. Scientists finetune asteroid bennu hitting. From the report: 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,' reports. NASA's OSIRIS-REx spacecraft has been orbiting an asteroid called Bennu for more than two years to fine-tune the agency's existing models of its trajectory.
