Giant asteroid to make ‘close approach’ with Earth this week, Nasa warns

AN enormous space rock will zip past Earth this week.

According to Nasa trackers, the asteroid 2013 BO76 will hurtle past on Thursday at a staggering 30,000 miles per hour (50,000 kph).

At up to 450 metres across, it’s roughly the same size as the Empire State Building.

Fortunately, the speedy object is expected to miss our planet by some distance.

It’ll fly by at a safe distance of around 3.1million miles, according to data on Nasa’s Near-Earth Object database.

That’s or 13 times the gap between Earth and the Moon – a near-miss in space terms.

The object has been added to Nasa’s list of upcoming “Close Approaches” – though it poses no danger to our planet.

Thousands of so-called near-Earth objects (NEOs) are tracked to provide an early warning if they shift onto a collision course with our planet.

Any space object that comes within 4.65 million miles of us is considered “potentially hazardous” by cautious space organisations.

According to Nasa’s Center for Near-Earth Object Studies, asteroid 2013 BO76 will make its close pass at 10:55 p.m. EST on Thursday (2:55 a.m Friday UK time).

It’s one of seven space objects expected to make what Nasa calls “close approaches” this week.

Fortunately, none of the asteroids being tracked by the space agency are thought to pose any danger to us.

Astronomers are currently tracking 2,000 asteroids, comets and other objects that could one day threaten our pale blue dot, and new ones are discovered every day.

Earth hasn’t seen an asteroid of apocalyptic scale since the space rock that wiped out the dinosaurs 66million years ago.

However, smaller objects capable of flattening an entire city crash into Earth every so often.

One a few hundred metres across devastated 800 square miles of forest near Tunguska in Siberia on June 30, 1908.

Fortunately, Nasa doesn’t believe any of the NEOs it keeps an eye on are on a collision course with our planet.

That could change in the coming months or years, however, as the space agency frequently revises objects’ predicted trajectories.

“Nasa knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small,” Nasa says.

“In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years.”

Even if one were to hit our planet, the vast majority of asteroids would not wipe out life as we know it.

“Global catastrophes” are only triggered when objects larger than 900 metres across smash into Earth, according to Nasa.
