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.

"Astronomers find Near-Earth Asteroids every day and most are harmless,” said Fitzsimmons, according to Phys.org.
“But it is still possible the next Tunguska would take us by surprise, and although we are much better at finding larger asteroids, that does us no good if we are not prepared to do something about them."
