From bbc.co.uk: A large asteroid is set to pass Earth in a close encounter which scientists say will pose no danger.
The asteroid, estimated at half a mile (800m) wide, will sweep within 270,000 miles (433,000km) of the planet - only slightly further away than the moon.
"It's not Earth-threatening," said Don Yeomans, who heads Nasa's Near Earth Object Program.
The asteroid, 2004 XP14, should be visible by telescope from N America and Europe, most clearly on Monday.
