One hundred leading scientists, astronomers, former astronauts and celebrities have called for more to be done to prevent a devastating asteroid strike.
TV physicist Professor Brian Cox is backing the campaign, as is Queen guitarist Brian May, who has a doctorate in astrophysics. He said: "The more we learn about asteroid impacts, the clearer it becomes that the human race has been living on borrowed time.” The group has called for a rapid increase in the discovery and tracking of near-Earth asteroids so that 100,000 can be discovered each year. There are believed to be millions of asteroids in the Solar System but only around 10,000 have been found to date.
The group wants June 30th next year to be declared Asteroid Day to promote efforts to prevent an impact. It was on that date in 1908 that around 800 square miles of forest in Tunguska, Siberia, was destroyed by an asteroid strike. A similar impact now could wipe out an entire city. Brian May said: "We are currently aware of less than 1% of objects comparable to the one that impacted at Tunguska, and nobody knows when the next big one will hit. It takes just one."
In February 2013 a meteor exploded in the skies above Chelyabinsk in Russia. Although nobody was killed it did cause widespread damage.
