Phew - Nasa says this will not happen (at least not this weekend)

Nasa has confirmed that a giant asteroid passed safely by Earth on Saturday - considered a near-miss at a distance of 15 million miles away.At 1.5 miles wide, a collision with asteroid 86666 (2000 FL 10) would be catastrophic. But on Friday Nasa's Jet Propulsion Lab's Near Earth Object Office, which tracks asteroids, said it would not come closer than 15m miles.
