Nasa has confirmed a giant asteroid they’ve been tracking, will pass by our planet on Tuesday 18th January.

The asteroid, named ‘(7482) 1994 PC1’ measures more than a kilometre in width, at 1,052m (3,451ft). To give you some perspective that’s taller than the world's tallest building Burj Khalifi in Dubai, which is 830m (2,723ft) high.

NASA's Asteroid Watch Twitter account assured its followers that the asteroid does not pose a threat to Earth.

1.2 million miles away from Earth, the asteroid will be passing about 5 times the moon's distance from Earth, at 43,754 miles per hour.

Astronomers believe this is the closest an asteroid will get to Earth for the next 200 years.

Robert McNaught first discovered asteroid (7482) 1994 PC1 at the Siding Spring Observatory in Australia on August 9, 1994.

It’s predicted to still be visible for any budding star gazers, with the help of a telescope.

How to see the asteroid:

SkyEarth recommends that star-gazers attach a camera to their telescope and set it to take exposures every 30 to 45 seconds.

It will appear as a point of light, like a star. Point the camera and telescope at a reference star or object in the trajectory of the asteroid.
