A METEOR with the explosive power of TEN cruise missiles has struck the Moon – sparking a massive explosion visible with the naked eye. And terrifyingly the 56,000 mph collision – captured by NASA scientists highlighting the catastrophic danger planet earth faces from similar meteors – was caused by a space rock weighing no more than 88 lbs (40 kilos). Despite the meteor’s tiny proportions – about the size of a small boulder and the weight of an average 10-year-old boy – the impact damage was colossal and the explosion shone with the brightness of a magnitude 4 star.
A similar strike against a city on earth would create a crater 65feet (20m) deep and create a devastating kill zone equivalent to TEN Tomahawk cruise missile striking in exactly the same place. Experts fear the death toll would run into thousands. Unlike the Moon the Earth has a protective atmosphere meaning most space debris burns up before it can impact.
But bigger meteors sometimes get through – most recently at Chelyabinsk in Russia where a 20 metre asteroid travelling at 43,000 mph breached the atmosphere and exploded with the power of 33 Hiroshimas.
A spokesman for respected science website Science.com said: “For the past eight years NASA has been monitoring the Moon for signs of explosions caused by meteors. “They’ve just seen the biggest explosion in the history of the programme.
