An asteroid worth a potential £3.5 trillion ($5.4 trillion) is due to pass by Earth on Sunday, and you can watch it live from 11pm UK time (6.30pm ET).
Asteroid 2011 UW-158’s fly-by will be streamed live on the internet from an observatory in the Canary Islands.
The space rock has attracted the attention of asteroid mining company Planetary Resources, because it is thought to have a 100 million ton core of platinum that the company might one day want to exploit.
Asteroid 2011 UW-158 will pass within 1.5 million miles (2.4 million km) from Earth on Sunday – 30 times closer than our nearest planet.
It is less than half a mile (1km) across, but is thought to be immensely valuable because of its platinum core.
