Iron, IIABWitnessed fall in Russia, February 12, 1947
Approximate Measurements: 28mm x 20mm x 11mm Please see one centimeter scale cube for size reference. The Sikhote-Alin meteorite is a famous witnessed fall that landed in Russia at 10:38 am on February 12, 1947. That morning an estimated 70-ton mass blasted through Earth's warm atmosphere at speeds of 25,000 mph or more. During its flight, experts estimate the surface of the Sikhote-Alin meteorite reached at least 3,000 degrees Fahrenheit.As the mass hurtled closer to our planet's crust, the pressure of ever-denser air forced it to shear and fracture along its crystalline planes, causing a monumental aerial explosion that was heard by human observers on the ground. The shockwave reportedly knocked over forest workers as twisted shards of metal rained down among snowy pines.Sikhote-Alin meteorites fall into two categories: shrapnel fragments, like this one, which are melted, torn, and blasted, resembling the remnants of wartime bombs. Others are complete pieces, their surfaces rounded and sculpted by ablation into fantastical shapes, and covered or partially covered with scalloped indentations called regmaglypts or thumbprints. These sculpted pieces, known as individuals, present beautiful natural formations and comprise only about 20% of all recovered masses.I.M.C.A. Member No. 3226. Shop confidently.
