Sneaky asteroid spotted whizzing between Earth and moon
A space rock large enough to do damage gives us a near miss just two days after being discovered.
An asteroid roughly the size of a 10-story building gave Earth a particularly close pass Monday morning.
2017 AG13 isn't so big it would have meant an extinction-level event had it been a direct hit. But if a good size chunk of it made it through Earth's upper atmosphere near a populated area, there might have been damage like we saw in 2013 when a bolide collided with the atmosphere over the Russian city Chelyabinsk. In that event, a fireball streaked over the city, releasing 500 kilotons of energy as it ran up against some serious resistance from Earth's atmosphere and exploded, blowing out windows all over town in the process.
