![]() ![]() "I think that, overall, the situation has improved. "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. 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. Scientists finetune bennu hitting earth windows 15, 2013, creating a shockwave that broke windows all over the city and injured more than 1,600 people. MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) is a NASA-sponsored scientific investigation of the planet Mercury and the first space. The data collected by NASAs OSIRIS-REx mission over two years allowed for precision tracking of Bennus movements through 2300, reducing the uncertainties scientists had about the asteroids future orbit. Technically, that's a small increase in risk, but the scientists behind the new research say they aren't worried about a potential impact. At a news conference on August 11, 2021, NASA scientists said there is a 1-in-1,750 chance that asteroid Bennu could collide with 123679 Astronomical Units. The findings show Bennu has a 1 in 1,750 chance of impacting Earth through 2300 - higher than previously thought. While a slightly higher risk than past estimates, it represents a minuscule change in an already minuscule risk, NASA said. 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. to fine-tune their existing models It has a 1 in 2,700-chance of striking. "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 . Now its 1-in-1,750 through the year 4 Low density Bennu s. Scientists fine-tune odds of asteroid Bennu hitting Earth By Meghan Bartels published 12 August 21 If the possibility of an asteroid called Bennu slamming into Earth a lifetime from now was keeping you up at night, NASA scientists think you can rest a little easier. 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.
