Check out the video where NASA explains what happened with the asteroid 2012 DA14 which was not detected by telescopes. Scientists used the infrasound sensors from the Comprehensive Test Ban Treaty Organization (CTBTO) to find the answers.
The asteroid was about 17 meters in diameter and weighed approximately 10,000 metric tons. It struck Earth’s atmosphere at 40,000 mph and broke apart about 12 to 15 miles above Earth’s surface. The energy of the resulting explosion exceeded 470 kilotons of TNT.
