Only slight chance of asteroid Bennu hitting Earth: NASA

An asteroid known as Bennu will pass within half the distance of the Earth to the Moon in the year 2135 but the probability of an impact with our planet in the coming centuries is very slight, scientists said Wednesday.

OSIRIS-REx, a NASA spacecraft, spent two years near Bennu, an asteroid that is about 1,650 feet (500 metres) wide, observing its size, shape, mass and composition and monitoring its orbital trajectory around the sun.
