An asteroid big enough to destroy London will narrowly miss the Earth as it flies past tonight, according to NASA.
The 150ft-wide rock has no chance of hitting the Earth scientists say, but it will enter the orbits of more than 100 telecommunication and weather satellites, just over 17,000 miles away from the planet.
It is thought it will reach its nearest point to Earth at 7.30pm (GMT) tonight.
The asteroid, 2012 DA14, was discovered by a spanish observatory a year ago.
