The Campo del Cielo meteorite is an IAB meteorite that is thought to have formed 4.5 billion years ago during the creation of our solar system. With a total recovered weight at 220,562 lbs (100,000 kg) it is possibly the heaviest meteorite to have ever been recovered on Earth.

The meteorite broke apart in the atmosphere and fell in the Chaco and Santiago del Estero Provinces of northwest Argentina. Radiocarbon dating of charred trees near the crater field placed the impact at around 2500 BCE. The oral history of indigenous groups informs us that the fall from the sky was witnessed and ignited massive forest fires.

This specimen is a sample of Campo del Cielo meteorite from Argentina. Like all IAB meteorites, it is made of meteoritic iron and reflects slightly in the light.

The specimen ships in a black charm box. A small information card that serves as certificate of authenticity is also included. Please note: there may be a slight odor when first opened, but the piece will air our. To polish, simply use a soft lint-free cloth.

With a recovered mass of 150 metric tons and boasting the largest documented strewnfield, Campo Del Cielo is an utterly unique meteorite.

The meteorite is an IAB-MG, meaning it is a part of the main group of non-magmatic iron meteorites. Although this group is far from rare, Campo Del Cielo is unique in that it has high levels of iridium, an element that does not occur naturally on the Earth’s surface and thus allows for easy identification.

Campo del Cielo is often referred to as a single meteorite, but in reality it is a broad term defining a meteorite field in the Santiago del Estero and Chaco provinces of northern Argentina. It is thought that the meteorite broke apart within the Earth’s atmosphere, with chunks spread across 20 mi² (55.5 km²). There are numerous large craters here, the largest being 377 by 299 ft (115 by 91 m), with radiocarbon dating of charred tree stumps placing the date of the impact at roughly 2500 BCE.

The descent and impact of the meteor was witnessed by local indigenous groups of the time and became an important part of their oral history. Stories from numerous tribes describe a cosmic event causing a worldwide fire that took many lives. This correlates with charred wood found around the site which suggests the meteorite may have ignited a forest fire upon impact.

The area was given the name Piguem Nonralta, first appearing in written history in 1576 CE, when Spanish colonists attempted to seek out the area. The governor of the provinces of Tucumán, Gonzalo de Abreu y Figueroa, believed the local legends spoke of a source of valuable metals which the indigenous peoples had used for weaponry. Translated into Spanish, the area became known as Campo del Cielo, meaning "Field of Heaven."

The 1576 expedition found the area and assumed it was an iron mine, the site going ignored until the late 1770s when a new expedition proposed that the iron field was the product of a volcanic eruption. It would not be until 1933 that the scientific community finally recognized the site as being formed by meteorite impacts, a fact the locals had known for millennia.
