The meteorite is considered to have broken off from a larger mass in the asteroid belt around 300 million years ago, before beginning its slow journey towards Earth. The present example fell to Earth over eastern Siberia on the 12th February 1947 as part of that famous event. Many of the eyewitnesses at the time thought the world was ending; a smoke trail streaked across the sky, shockwaves from the explosion shattered windows and uprooted trees and sonic booms were heard hundreds of miles away.
