Once it arrived in Germany, the Iron Man became part of a private collection and it wasn't until 2009 that cientists could study it, following an auction.
Weighting about 23 pounds, the statue wasn't exactly carved from the most appropriate material.
Buchner and colleagues noted that the artist who created it from the extremely hard meteorite may have known that the material was special.
"The fall of meteorites has been interpreted as divine messages by multitudinous cultures since prehistoric times," they wrote.
According to Buchner, the statue was likely carved about 1,000 years ago by the pre-Buddhist Bon culture of the 11th century.
However, the exact origin and age of the statue remains unknown.
"While the first debris was officially discovered in 1913 by gold prospectors, we believe that this individual meteorite fragment was collected many centuries before," Buchner said.
Although other meteorites are known to have inspired worship from many ancient cultures, the Iron Man statue is pretty unique.
