It was a 5-kilogram (11 lb) Martian meteorite which fell to Earth at Shergotty (now Sherghati), in the Gaya district, Bihar, India on 25 August 1865, and was retrieved by witnesses almost immediately. Radiometric dating indicates that it solidified from a volcanic magma about 4.1 billion years ago.
