NASA asteroid revelation: Why researcher claimed space rock 'threatens' Earth

Asteroid are the small rocky bodies that in the inner Solar System, orbiting the Sun. There are millions of them flying around space and their collisions – known as impact events – have played a significant role in shaping many planets. Many of these space rocks, including Apophis 99942, are of great interest to NASA, due to their potential to create global devastation should they strike Earth.

Observations made by the space agency in 2013 pretty much ruled out the possibility of an impact in the future for Apophis, pinning a one in 150,000 chance for 2068.

However, researchers revealed why they believe there is proof we will see another large asteroid event sometime soon during Amazon Prime’s “Spacefiles”.

Presenter Roger Liddle explained: “Most impacts happened when the planets first formed. 

“These are Martian craters, imprints of primordial debris from four-and-a-half billion years ago when the solar system was a maelstrom of colliding bodies. 

“But on our serene planet, where are the impacts?

“We have them if you know where to look.”

The series then jetted down under to reveal the scars of previous impacts.

Mr Liddle added: “Australia, dry and geologically stable, is one of the best places to find a crater. 

“In the heart of the outback, these are the Henbury craters.

“They were blasted by an impactor that had broken into pieces.

“Most craters on Earth are quickly eroded by weather, but these survived.”

Mr Liddle went on to reveal why the craters prove we will see another similar event soon.

He continued: “The Henbury impacts happened just five thousand years ago and is evidence that Earth and the Moon are still threatened by projectiles from space.

“To find their source we travel away from the Sun. 

“Through space long cleared of interplanetary trash, we head beyond Mars. 

“Out here, in the great void before Jupiter, is the asteroid belt.”
