An asteroid is set to pass close to earth next week, zipping past our planet at roughly one-eighth of the distance to the moon.
Nasa has estimated the rock to be around 10 to 30 metres in diameter, according to RT. That's roughly the size of the Chelyabinsk meteor, which penetrayed earth's atmosphere in 2013 and damaged a number of buildings, leaving 1,000 people injured by flying glass.
The asteroid is expected to be travelling at a speed of about 30,000 mph and be roughly 27,000 miles from earth next Thursday (October 12)
Despite the the asteroid passing so closely, last year Nasa had predicted that it may come even closer, a distance of just 4,200 miles from earth.
However, there is no need to worry as it shouldn't threaten earth at all. In fact the flyby is thought to have potentially positive consequences for our planetary defence system; Nasa has said it use the passing rock to test “recovery, characterisation and reporting of a potentially hazardous object approaching Earth."
The US space agency has also said it will look at its worldwide asteroid detection and tracking network and find out more about its capabilities in case of an asteroid which could threaten the planet.
