Campo del Cielo is a large iron meteorite weighing 50 tons. The meteorite fell about 4,600 years ago, 800 km northwest of Buenos Aires in the provinces of Chaco and Santiago del Estero in modern-day Argentina. Only about 5% of meteorites found on Earth contain iron, so the Campo del Cielo material is very valuable for collecting. Incredible specimens of this meteorite can be found in museums and private collections around the world.
