NASA stated that while it is a higher risk than previous estimates, it is still a small change to an already minimal risk.Related: NASA spacecraft leaves Bennu asteroid to bring parts to EarthContinue reading: OSIRIS-REx team creates Bennu photosOSIRIS-REx captured an image of Bennu, the asteroid. NASA reported that estimates made before OSIRIS REx reached the space rock put the cumulative probability for a Bennu-impact between 2175-2199 at 1 in 2,700. Experts studying possible space rock impacts with Earth were able to get a detailed view of the asteroid and fine tune their models of Bennu’s future.Scientists behind new research are now confident that the asteroid's total probability of impact through 2300 is only 1 in 1,750. 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.OSIRIS-REx, the OSIRIS spacecraft of the agency, spent over two years orbiting this space rock.
