Twenty days ago, according to the Telegraph , "scientists had no clue a thirty-foot meteor was hurtling toward the Earth until it exploded with the force of 50,000 tons of TNT, in the atmosphere."
Scientists are concerned that it was not spotted by any telescopes, and that had it been larger it could have caused a disaster.
Luckily, due to the height of the explosion – estimated at between 15 and 20 km (nine to 12 miles) above sea level – no damage was caused on the ground.
However, if the object had been slightly larger – 20 to 30 metres (60 to 90ft) across – it could easily have caused extensive damage and loss of life, say researchers.
Very few objects smaller than 100 meters (300ft) across have been spotted and catalogued by astronomers.
Looks like this is a good time as any to review your Bucket Lists. Or snag that elusive boyfriend. Or finally decide if you're gay, straight, curious, bi, confused, or mineral.
Me, I'm going to look at cars.
