It's one of five large asteroids that will hurtle past Planet Earth this week.

The asteroid is about four times the size of the CN Tower and is travelling at more than 30,000 kilometres per hour.

Astronomers say the relatively tiny object has been circling the Earth for about three years — but it won‘t be around for much longer.

A kilometre-wide asteroid is scheduled to whip past Earth on Feb. 15, according to NASA.

Experts say Saturday's fireball over Alberta likely deposited space rocks somewhere south or southwest of New Serepta, Alta.

The asteroid passed much closer to Earth than the moon, and would have triggered a nuclear-sized explosion if it hit us.

The Tunguska event was a huge explosion that levelled over 2,000 square kilometres of forest in Siberia in 1908.

The space agency shared images the rovers beamed back to Earth showing the robots’ approach and surface landing.

An asteroid that's estimated to be the size of the Statue of Liberty will narrowly miss Earth as it passes by on May 15.

Scientists are exploring whether a series of spacecraft launches could be used to deflect asteroid Bennu off-course and prevent it from striking the Earth.
