![]() The asteroid will make its next closest approach to Earth in 2135. While Bennu won't come close enough to pose a threat to Earth then, knowing its exact trajectory can help scientists better understand how the gravity of our planet will change the asteroid's future orbit around the sun. This could also affect the chances of Bennu impacting Earth after 2135.īennu will make its most significant close approach on Sept. 24, 2182, with a 1 in 2,700 chance of impacting Earth on that day. The researchers agree that the risk of Bennu impacting Earth is low, and NASA will continue to observe the asteroid's orbit for years to come. The OSIRIS-REx mission, or Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer, arrived at Bennu in December 2018 and departed earlier this year on May 10.

Maybe the possibility of an asteroid hit will generate more post-asteroid apocalypse sci-fi. An asteroid hit is believed to have wiped out the dinosaurs and many other types of life forms 66 million years ago. NASA has catalogued 26,000 near-Earth asteroids so far. Meghan Bartels, “ Scientists fine-tune odds of asteroid Bennu hitting Earth through 2300 with NASA probe’s help” at (August 11, 2021)Ī paper discussing the Osiris Rex’s findings is open access. How precisely that dance plays out will shape Bennu’s trajectory over the next decades and centuries. In September of that year, Bennu will swing past Earth - not close enough that there’s any risk of an impact, but certainly close enough that Earth’s gravity could nudge the asteroid a bit on its path. However, despite the scientists’ best efforts, predicting Bennu’s course after 2135 is still tricky. That uncertainty remains even in the new and improved models of Bennu’s future path, but with the OSIRIS-REx observations, scientists were able to dramatically reduce their uncertainty about Bennu’s fate… Scientists’ models of asteroid trajectories always include some degree of uncertainty, since a multitude of forces tug at a space rock as it rattles around the inner solar system.
