Summary
It marks the closest asteroid flyby ever recorded in which the object actually survived, according to NASA.For comparison, the International Space Station is 254 miles away."Near-Earth Asteroids (NEAs) pass by Earth all the time, but 2020 QG passed closer to Earth than any other known NEA without actually impacting," a NASA spokesperson told CBS News on Tuesday.2020 QG was first observed at the Palomar Observatory a whopping six hours after it passed over the southern Indian Ocean."It's quite an accomplishment to find these tiny close-in asteroids in the first place, because they pass by so fast," said Paul Chodas, director of the Center for Near-Earth Object Studies (CNEOS) at NASA's Jet Propulsion Laboratory in Southern California.
