The meteor strike that injured hundreds of people in Russia earlier this year could have been much more dangerous according to new research, and scientists say it “shows that the Earth is vulnerable”.
The violent explosion on February 18 saw the 20-metre space rock split into fragments miles above the city of Chelyabinsk and was the biggest blast of its kind in more than 100 years.
It briefly outshone the sun and inflicted severe burns on observers below, as well as smashing windows and rattling buildings.
But researchers say a more solid rock would have caused greater damage and casualties.
