While the odds of a strike have risen from 1-in-2,700 to 1-in-1,750 over the next century or two, scientists now have a much better idea of Bennu’s path thanks to NASA’s Osiris-Rex spacecraft, according to Farnocchia. “So I think that overall, the situation has improved,” he told reporters. The spacecraft is headed back to Earth on a long, roundabout loop after collecting samples from the large, spinning rubble pile of an asteroid, considered one of the two most hazardous known asteroids in our solar system. That uncertainty remains even in the new and improved models of Bennu’s future path, but with the OSIRIS-REx observations, scientists have been able to drastically reduce their uncertainty about Bennu’s fate … The samples are due here in 2023.Scientists’ patterns of asteroid trajectories always include some degree of uncertainty, as a multitude of forces drag a space rock as it rattles around the inner solar system. However, despite the best efforts of scientists, predicting Bennu’s course after 2135 is still difficult. ![]() Within that time period, the most concerning date is Sept. In September of that year, Bennu will swing past Earth, not close enough not to risk an impact, but certainly close enough for Earth’s gravity to push the asteroid a little in its path. 24, 2182 even on that day, Bennu’s impact probability is only 1 in 2,700. Beyond Bennu Of course, Bennu isn’t the only space rock that scientists worry about. Planetary defense is dedicated to identifying all asteroids that could potentially impact Earth in a meaningful way. ![]() The precision with which that dance takes place will shape Bennu’s trajectory over the next decades and centuries. Meghan Bartels, “Scientists fine-tune the odds of asteroid Bennu hitting Earth until 11pm with the help of the NASA spacecraft” on (11 August 2021)Ī paper discussing Osiris Rex’s findings is open access. ![]() NASA can use Osiris-RExs observations to fine-tune their understanding of. So far, NASA has cataloged 26,000 asteroids near Earth. Sure, Bennu only has a smidgen of a chance to hit Earth, but NASA would like. If you could live forever, would you?

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.
