  Washington (AFP) Aug 19, 2020 An asteroid the size of an SUV passed 1,830 miles (2,950 kilometers) above Earth, the closest asteroid ever observed passing by our planet, NASA said Tuesday. If it had been on a collision course with Earth, the asteroid - named 2020 QG - would likely not have caused any damage, instead disintegrating in the atmosphere, creating a fireball in the sky, or a meteor, NASA's Jet Propulsion Laboratory (JPL) said in a statement. The asteroid, which was about 10 to 20 feet (three to six meters) long, ... read more |
