NewScientist: Tunguska-sized space rock buzzes Earth

An asteroid about the size of the one that levelled the forest in Tunguska, Siberia, a century ago flew past Earth on Monday - well within the Moon's orbit. The risk of a future impact with the object is not yet known.
The asteroid, dubbed 2008 DD45, whizzed just 72,000 kilometres above the Earth's surface. That is less than a fifth of the distance to the Moon and just twice the distance to geosynchronous satellites. Full story:
