Campo del Cielo meteorites are iron meteorites that are found in an area 620 miles northwest of Buenos Aires, Argentina, between the provinces of Chaco and Santiago del Estero. There are 26 separate impact creates, all estimated between 4000 and 5000 years old, with the largest being 377 by 299 ft. If that is not a cool enough reason to own a meteorite, we don't know what is!
