Scientists have been tracking asteroid 101955 Bennu ever since it was discovered in 1999, in part because its orbit occasionally brings it close to Earth, raising the risk of a future crash.
At about 500 meters (1,600 feet) wide, the asteroid could wipe out a city if it impacted a populated area of our planet, though it would not wreak the kind of planetary damage caused by the Chicxulub impactor, which spanned at least 10 kilometers (6 miles) and ended the age of the dinosaurs.
Now keep In mind that we were talking about a 22nd century impact. So this one has no danger to us in the immediate future.. great great great great great grandchildren may face another reality ..
