NASA is eyeing an asteroid that’s bigger than a skyscraper

Asteroid Bennu regularly approaches Earth at close range, about once every six years. This massive space object, about 49 meters in diameter, was discovered in 1999, and NASA astronomers keep a close eye on it. There is a danger that Bennu could enter Earth’s orbit and collide with it on September 24, 2182. If that happens, the impact would release 1,200 megatons of energy.
Although the likelihood of a collision with Earth is currently low, Bennu has been classified as a “potentially hazardous asteroid”: it could come within 7.48 million kilometers of us.
