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. Scientists Fine-Tune Odds of Asteroid Bennu Hitting Earth () 49 Posted by BeauHD on Thursday Aug06:00AM from the you-can-rest-a-little-easier dept. New ultraprecise measurements show that the asteroid Bennu has a higher chance than thought of impacting our planet sometime in the next 300 years, NASA says. Hear the biggest stories from the world of science 18 March 2021. "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. ![]() NASAs OSIRIS-REx spacecraft has been orbiting an asteroid called Bennu for more than two years to fine-tune the agencys existing models of its trajectory. Also known as asteroid 99942, the near-Earth object is estimated to be about 1,100 feet (340 meters) across and could cause serious damage to the planet's surface if it were to hit. Submitted at the Department of Philosophy, Logic and Scientific Method. sudden and inexplicable increase in the number of asteroids hitting us because this. Where anthropic reasoning does lead to chances that are observer-relative in an. NASA scientists believe that if the possibility of Bennu, an asteroid hitting Earth in a few years is keeping you awake at night you can now rest easier. 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. While a slightly higher risk than past estimates, it represents a minuscule change in an already minuscule risk, NASA said. Technically, that's a small increase in risk, but the scientists behind the new research say they aren't worried about a potential impact.

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. ![]() As a result, scientists behind new research now say theyre confident that the asteroids total impact probability through 2300 is just 1 in 1,750. "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. In 1959, Arthur Samuel defined machine learning as a. "I think that, overall, the situation has improved.
