Asteroid zooms past Earth at half the distance to the Moon
An asteroid measuring about 50-120 metres width flew past Earth at speed of 46,000 kmph on Wednesday early morning. Asteroid 2010 WC9 made the closest approach at about 2,00,000 km from Antarctica, which is over half the distance between Earth and the Moon. This flyby is the closest approach the asteroid will make for at least two centuries, said NASA.
