It may not look like much, but this is the asteroid big enough to flatten London that narrowly missed the Earth tonight. The 150ft-wide space rock came as as close as 17,200 miles to Earth's surface.
The asteroid, given the name of 2012 DA14, has been closely tracked since its discovery by a Spanish observatory a year ago.

Despite cloudy skies, scientists at the Bayfordbury Observatory at the University of Hertfordshire are still hoping to get a glimpse of the asteroid in the next 90 minutes.
The asteroid, given the not so catchy name of 2012 DA14, has been closely tracked since its discovery by a Spanish observatory a year ago. It is predicted to reach its nearest point to Earth at around 7.30pm tonight UK time.
Sky watchers have been told that given clear skies they should be able to track the rock climbing in the north-eastern sky from anywhere in the UK.
An asteroid called 2012 DA14 will narrowly miss Earth as it flies past at 7pm tonight.
The 45 metre diameter rock is big enough to destroy London.
It has no chance of hitting, but it will enter the orbit of more than 100 satellites.
It is expected to fly 17,200 miles (27,000 kilometres) above Earth's surface at around 7pm GMT.
The flyby of 2012 DA14 is the closest-ever predicted approach to Earth for an object this large.
There's speculation that the meteor could be linked to an asteroid that will pass through satellite space later today.
It is believed to be 50 metres wide and capable of wiping out a city the size of London and is expected to miss Earth by a distance of over 17,000 miles but is the closest ever predicted for an object of that size.
Astronomer Nigel Henbest told ITV News the asteroid is not linked to the Russian meteor:
An asteroid is expected to pass between the Earth and the moon this evening.
Although it will not hit Earth, it could hit one of its surrounding satellites.
Space journalist and Astrophysicist Sarah Cruddas told Daybreak that scientists knew very little about asteroids.
She said studying them can help provide a better understanding as to why we came to be here on the Earth.
