An asteroid capable of destroying London will skim past the Earth on Friday, approaching closer than many satellites.
Scientists say there is no chance the 150ft-wide space rock will hit the planet. But it could collide with one of more than 100 telecommunication and weather satellites in fixed orbits above the Earth.
The asteroid, 2012 DA14, has been closely tracked since its discovery a year ago. It is predicted to reach its nearest point to the Earth at around 7.30pm on Friday.
