It posed no danger, but was the third-closest fly-by of our planet. The asteroid that will be knocked off course is six million miles away and is no threat to Earth now, scientists say, adding that the DART mission will not make it a danger either.

In September, NASA announced that a new study raised the possibility that the asteroid Bennu could hit Earth sometime by 2300.At 1,600 feet across, it is a potentially hazardous object. The DART mission aims to shift an asteroids orbit through kinetic impact specifically by smashing a spacecraft into the smaller member of the binary. by Alan Boyle on November 23, 2021 at 11:30 pm. Later calculations let NASA scientists announce on March 26, 2021, that Earth is safe from an impact with the relatively large asteroid for at least the next 100 years.

Impact should take place in the fall of 2022, when the binary asteroid system is 6.8 million miles (11 million kilometers) from Earth, almost the nearest point they ever get.

Earth has already had a close call with another asteroid, called 1998 SD9, in October. Bennu is classified as a potentially hazardous asteroid, or PHA. There is a small (1 in 2,700) chance that Bennu will hit Earth late in the 22nd century. If Bennu did hit Earth, it would release the energy equivalent of 1,450 megatons of TNT, creating an impact crater about 5 kilometers (about 3 miles) in diameter.
