Asteroid danger: Scientists unveil extreme plan to intercept rock the size of a skyscraper

SCIENTISTS have scrambled to find ways to prevent asteroids from smashing into the Earth’s surface causing a catastrophic impact.

A number of theories have been suggested as ways to stop the Earth from being catastrophically hit by the impact of an  on a path to hit the planet. Although there are currently no asteroids which are on track to hit the planet, scientists have discussed potential ways of stopping devastating impacts. Pete Worden, adviser on space resources to the Grand Duchy of Luxembourg, told ABC News if an asteroid was a big enough threat to the planet “we'll go move them”.

In 2021, NASA’s Double Asteroid Redirection Test will take place, essentially demonstrating the kinetic effects of bumping into a small asteroid to detect how much they can move its path - in a way to defend the planet in the future.

Mr Wordon said: “The thing is, if you move something years in advance, you don't have to move it very much.

“This is a rock that's the size of a skyscraper.

“You would then hit it with a spacecraft kind of the size of a small car, and by impacting it, it impacts energy and momentum and will move it slightly off its orbit.”

The theory is that a small impact on an asteroid that was expected to come within 2,000 miles of Earth would eventually glide past by thousands of miles away.

Wordon also claimed spray painting one side of an asteroid was being discussed, as that patch would then be heated differently by the Sun, impacting its path.

The expert also told ABC News discussions around a “giant laser” or using a “modest-sized spacecraft” to move an asteroid over a lengthy period of time.

It comes as an asteroid bigger than the Eiffel Tower, dubbed 2006 QQ23, which is travelling at a speed of 10,400mph, hurtled near past the Earth over the weekend.

The asteroid, known as 2006 QQ23, could have hit with a force 500 times that of the atomic bomb dropped on Hiroshima, had it been travelling along a different trajectory.

2006 QQ23 hurtled past Earth on Saturday, in what is believed to be the closest call of an asteroid hitting the planet since 2001.

Although 2006 QQ23 missed Earth by 4.6 million miles, NASA considered the asteroid to be “potentially hazardous”.

Danica Remy, president of the nonprofit organisation B612 Foundation, works to protect the planet from asteroids.

She said: “It’s 100 percent certain that we’re going to get hit, but we’re not 100 percent certain when.”

She added: "The real issue is that we need to have an inventory of all the asteroids."

NASA Administrator Jim Bridenstine has previously warned about the dangers of an asteroid collision, commenting: “We have to make sure that people understand that this is not about Hollywood, it's not about the movies.

“This is about ultimately protecting the only planet we know, right now, to host life - and that is the planet Earth.”

The warning comes as a 99 metres in diameter asteroid prepares for a near miss of Earth on Friday.

While PJ will safely pass us by, another 500 metre space rock is providing for more cause for concern.

which will take samples from the monster asteroid.

And experts fear there is a one in 24,000 chance the space rock could hit earth in 120 years time.
