In 2135, asteroid Bennu will make a close flyby of Earth. Our planet’s gravity will tweak Bennu’s path, making it a challenge to calculate its future trajectory.

While the University of Arizona-led OSIRIS-REx mission studied and sampled the asteroid Bennu, it was also helping scientists calculate if — or when — the half-kilometer body will one day slam into the Earth.
Their findings appear in the journal Icarus.
Sept. 24, 2182: In the next 300 years, that’s when Bennu has the best chance of striking Earth: roughly .05%.
To figure that out, the team accounted for everything from hundreds of gravitational nudges to minute thrusts from surface heating and particle ejection.
