Their findings - published in the journal Icarus - should also help in charting the course of other asteroids and give Earth a better fighting chance if and when another hazardous space rock heads our way.īefore Osiris-Rex arrived on the scene, scientists put the odds of Bennu hitting Earth through the year 2200 at 1-in-2,700. ![]() The spacecraft collected enough data over 2 1/2 years to help scientists better predict the asteroid’s orbital path well into the future. The samples are due here in 2023.īefore Osiris-Rex arrived at Bennu in 2018, telescopes provided solid insight into the asteroid, about one-third of a mile in diameter. 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. ![]() “So I think that overall, the situation has improved," he told reporters. 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. “We shouldn't be worried about it too much,” said Davide Farnocchia, a scientist with NASA's Center for Near Earth Object Studies at the Jet Propulsion Laboratory in Pasadena, California, who served as the study's lead author. But don’t be alarmed: Scientists reported Wednesday that the odds are still quite low that Bennu will hit us in the next century. ![]()
