The Gancedo Meteorite is the largest known fragment of the meteor shower that fell in Campo del Cielo, in Charata, Chaco Province, Argentina.[1]
According to early reports, the meteorite weighs approximately 30,800 kilograms (34.0 short tons), making it the largest meteorite found in the Americas and the third-largest in the world. Before 2016, El Chaco, also part of the Campo del Cielo meteorite fall, was estimated to be the largest fragment of this meteor shower. Its weight was estimated at 37,000 kilograms (41 short tons) but was re-estimated at 28,840 kilograms (31.79 short tons) in 2016.[1]
It makes Gancedo the third-largest worldwide, while Anighito, part of the massive Cape York meteorite fall found in Greenland, weighs 30,875 kilograms (34.034 short tons).[2] The largest single-piece find remains the Hoba meteorite, which was estimated at 60,000 kilograms (66 short tons).
