'Potentially hazardous' asteroid may fly past Earth on Feb 4
A 1.1-km-wide asteroid classified as "potentially hazardous" by NASA will reportedly fly past Earth at a speed of over 1 lakh kmph on February 4. Called 2002 AJ129, it would fly by over 10 Earth-Moon distances away. An impact could cause global average temperatures to fall by 8Â°C, however, astronomers said there's little chance of the asteroid hitting the planet.
