Asteroid explosion over Indonesia raises fears about Earth's defences

On 8 October, the rock crashed into the atmosphere above South
Sulawesi, Indonesia. The blast was heard by monitoring stations
10,000 miles away, according to a report by scientists at the
University of Western Ontario.
Scientists are concerned that it was not spotted by any
telescopes, and that had it been larger it could have caused a
disaster.
The asteroid, estimated to have been around 10 metres (30ft)
across, hit the atmosphere at an estimated 45,000mph. The
sudden deceleration caused it to heat up rapidly and explode
with the force of 50,000 tons of TNT.
