The Kamchatka meteor was a meteor that exploded in an air burst off the east coast of the Kamchatka Peninsula in eastern Russia on 18 December 2018.[3] At around midday, local time,[4] an asteroid roughly 10 meters in diameter entered the atmosphere at a speed of 32.0 km/s (72,000 mph), with a TNT equivalent energy of 173 kilotons, more than 10 times the energy of the Little Boy bomb dropped on Hiroshima in 1945.[3] The object entered at a steep angle of 7 degrees, close to the zenith, terminating in an air burst at an altitude of around 25 km (16 mi; 82,000 ft).[3][5]
