Krasnojarsk was the first pallasite meteorite ever found.

History[edit]

A mass of about 700 kilograms (1,500 lb) was detected in 1749 about 145 miles south of Krasnoyarsk. It was seen by P.S. Pallas in 1772 and then, on his orders, transported to Saint Petersburg.

Krasnojarsk was the first pallasite meteorite ever found and studied and lead to the creation of the Pallasite group named after Pallas. It was also the first meteorite ever etched with acid (by G. Thomson) and therefore was the first one to show to human eyes the Widmanstätten pattern.

The main mass of 515 kilograms (1,135 lb) is now in Moscow at the Academy of Sciences.
