Wow! millions of people could have died yesterday, if perhaps some random intergalactic tug pushed the sucker on a trajectory towards earth.

An asteroid which may be as big as a ten-storey building has passed close by the Earth, astronomers say.
The object, known as 2009 DD45, thought to be 21-47m (68-152ft) across, raced by our planet at 1344 GMT on Monday.
The gap was just 72,000 km (44,750 miles); a fifth of the distance between our planet and the Moon.
It is in the same size range as a rock which exploded over Siberia in 1908 with the force of 1,000 atomic bombs.
