It is natural to wonder if this event has any connection to today's record-setting flyby of asteroid 2012 DA14. NASA has issued the following statement:
"The trajectory of the Russian meteorite was significantly different than the trajectory of the asteroid 2012 DA14, making it a completely unrelated object. Information is still being collected about the Russian meteorite and analysis is preliminary at this point. In videos of the meteor, it is seen to pass from left to right in front of the rising sun, which means it was traveling from north to south. Asteroid DA14's trajectory is in the opposite direction, from south to north."

This is the most energetic recorded meteor strike since the Tunguska impact of 1908. Researchers have conducted a preliminary analysis of the event. "Here is what we know so far," says Bill Cooke, head of NASA's Meteoroid Environment Office. "The asteroid was about 15 meters in diameter and weighed approximately 7000 metric tons. It struck Earth's atmosphere at 18 km/s and broke apart about 20 to 25 km above Earth's surface. The energy of the resulting explosion was in the vicinity of 300 kilotons of TNT."
