Hi All:

Reconstructing the Chelyabinsk meteor's path, with Google Earth, YouTube and
high-school math... a very interesting article:

According to some:

"NASA has revised their size and energy estimates for the Russia meteor upon
review of further data. Scientists now believe the small asteroid was about
17 meters, or 55 feet, in diameter and had a mass of 10,000 tons. The
revised estimate of energy unleashed by the meteor is about 500 kilotons,
more than 30 times the blast yield of the atomic bomb dropped on Hiroshima."

A very impressive world event.
