The energy estimate was later increased to 470 kilotons.

But late Friday, NASA revised its estimates on the size and power of the devastating meteor explosion. The meteorís size is now thought to be slightly larger ó about 55 feet (17 m) wide ó with the power of the blast estimate of about 500 kilotons, 30 kilotons higher than before, NASA officials said in a statement.

The meteor was also substantially more massive than thought as well. Initial estimated pegged the space rockís mass at about 7,000 tons. Scientists at NASAís Jet Propulsion Laboratory in Pasadena, Calif., now say the meteor weighed about 10,000 tons and was travelling 40,000 mph (64,373 km/h) when it exploded.
