The closest observed asteroid yet to skim past the Earth without hitting the
atmosphere, was reported by astronomers on Sunday.

The previously unknown object, spanning five to 10 metres across, has been
named 2004 FU162. It streaked across the sky just 6500 kilometres - roughly
the radius of the Earth - above the ground on 31 March, although details
have only now emerged.
