During that time, the spacecraft gathered information about Bennu’s size, shape, mass, and composition while monitoring its spin and orbital trajectory. 11, to discuss an important finding from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft.OSIRIS-REx spent over two years near the asteroid Bennu, which is a third of a mile (500 meters) wide. NASA will host a media teleconference at 1 p.m. Now, a new paper from the OSIRIS-REx science team gives Bennu a 1:2700 (0.037%) chance of impacting Earth on September 24, 2182.Learn more about asteroid Bennu's updated impact hazard. During the flyby, there is an extremely small chance that Bennu will pass through a “gravitational keyhole” – a region of space that would set it on just the right path to impact Earth, late in the 22nd century.Although it is difficult to determine the odds of this actually happening, new data from NASA’s OSIRIS-REx spacecraft have allowed scientists to better model how Bennu’s orbit will evolve over time, and to better calculate the probability of an impact. Our planet’s gravity will tweak Bennu’s path, making it a challenge to calculate its future trajectory. || On September 25, 2135, an asteroid called Bennu will make a close flyby of Earth. OSIRIS-REx is improving our understanding of asteroid Bennu’s future impact hazard.Complete transcript available.Universal Production Music: “Time Particles” by Laetitia FrenodWatch this video on the NASA Goddard YouTube channel.
