The space rock, which could be up to 40 metres in size, making it bigger than the largest ever creature to have lived on Earth – the blue whale – is set to come in close proximity with our planet at 10.30pm GMT.
For anyone wanting to watch the asteroid’s flyby, the Virtual Telescope Project will be hosting a live stream from location in Italy, beginning at 8pm GMT.
A statement from the Virtual Telescope reads: “The observatory is placed at 1300 meters above the sea level, in the Sonoran desert, providing one of the best skies in the world.”
The asteroid will be travelling at hypersonic speeds as it flies by at close to five miles per second – making it four times faster than the speediest ever man-made machine, the North American X-15 which can travel at 4,520 miles per hour.
The rock could be up to 40 metres wide which would be double the size to the meteor which almost wiped out Chelyabinsk.
In 2013, a 20 metre meteor exploded over the Russian city which smashed windows and caused injuries to more than 1,000 people.
Experts say it is likely to be between 15 to 40 metres in size and that space rocks like these only come this close “once or twice” a year.
Paul Chodas, manager of the Centre for Near-Earth Object Studies at Nasa’s Jet Propulsion Laboratory, said: “Although 2018 CB is quite small, it might well be larger than the asteroid that entered the Atmosphere over Chelyabinsk, Russia, almost exactly five years ago, in 2013.
“Asteroids of this size do not often approach this close to our planet – maybe only once or twice a year.”
