Siberian Meteor

Amazing videos of a meteor exploding over Russia this morning.

Later today Asteroid 2012 DA14 is going to pass within 27,000 km of earth, closer than geosynchronous orbit. It's 45 meters in diameter. If DA14 hit earth, it would result in a 3 megaton explosion.

The famous Tunguska Event of 1908 is estimated at 10-15 megatons, and flattened trees (see right) over 2000 square km.

For less dramatic but just as beautiful meteors, the next shower is the Lyrids on April 22.
