Scientist: Dangerous Asteroid Could Hit Earth At Any Moment

An astrophysicist has warned that Earth could be hit with a surprise asteroid strike, according to news reports.

Professor Alan Fitzsimmons, an astronomer at the Queen’s University Belfast Astrophysics Research Centre highlighted the threat ahead of Asteroid Day on June 30, according to Phys.org.

Fitzsimmons reportedly warned that it is a case of when, rather than if, an asteroid collision will happen.

June 30 marks the 109th anniversary of the “Tunguska event” in Siberia – the largest-ever recorded explosion of a space object plunging to Earth. The blast, which was later attributed to a comet or asteroid fragment, is generally estimated to have been about 10 megatons. No injuries were reported, but some 80 million trees over 830 square miles were leveled.

The astrophysicist warns that a similar strike could destroy a major city, and a large asteroid could prove even more dangerous, Phys.org reports.

“It is important to know that scientists and engineers have made great strides in detecting Near-Earth Asteroids and understanding the threat posed by them,” he said. “Over 1,800 potentially hazardous objects have been discovered so far, but there are many more waiting to be found.”

Last year NASA opened a new office to track asteroids and comets that come too close to Earth. The Planetary Defense Coordination Office (PDCO) formalizes the agency’s existing program for detecting and tracking Near-Earth Objects, known as NEOs.
