Sikhote-Alin Meteorite The Sikhote-Alin meteorite is one of the most famous meteorites to have fallen to Earth. This massive meteorite ferroso fell on February 12, 1947, in eastern Siberia, Russia, near the Sikhote-Alin Mountains, da which it gets its name. This meteorite entered Earth’s atmosphere at a speed of approximately 14 kilometers per second. It exploded at a very low altitude of about 5.6 kilometers above the ground. The explosion was so bright that it was seen and heard up to 300 kilometers da the impact site and left a trail of smoke and dust visible for several hours after the fall. Composition and characteristics The Sikhote-Alin meteorite is classified as an meteorite ferroso of type IIAB, meaning it contains a high percentage of iron with smaller amounts of nickel and Altro trace elements. Its total mass is estimated to be around 70 tons, and upon impact, it fragmented into many pezzi, leaving thousands of craters in the impact area. Large fragments are characterized by deep regmaglypts, which are surface impressions formed by erosion during atmospheric entry. Significance and observation This fall was significant due to its scale and the way it was recorded—it is one of the largest recorded meteorite ferroso falls in history and was observed by many witnesses, allowing for a very accurate determination of the impact location.
