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 (one-half kilometer) 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.
The bad news is that the space rock has a slightly greater chance of clobbering Earth than previously thought.īut don't be alarmed: Scientists reported Wednesday that the odds are still quite low that Bennu will hit us in the next century. (AP) - The good news is that scientists have a better handle on asteroid Bennu's whereabouts for the next 200 years.
