Asteroid flies by Earth closer than any seen before, Nasa says

An asteroid has flown past Earth closer than any seen before. The tiny object, known as asteroid 2020 QG, came just 1,830 miles over the southern Indian Ocean on Sunday, the space agency said. As it did so, it was spotted by the Zwicky Transient Facility, a robotic camera that scans the sky in search of a variety of objects, from the smallest asteroids to the largest supernova. The asteroid 2020 QG is particularly small. It is about three to six meters across, scientists said, roughly the size of a large car.
