Meteorite
The Hoba meteorite, lying where it was discovered in 1920 near Grootfontein, Namibia. The largest meteorite on Earth and an iron meteorite by classification, it consists of a nickel-iron alloy and is estimated to weigh about 60 tons.
Pallasite meteorites are a type of stony iron meteorite characterized by a coherent mass of nickel-iron metal that encloses separated stony parts, which consist of silicates.
These meteorites are believed to have formed within the parent asteroid following a process of melting and differentiation. Specifically, they are thought to have originated at the interface between the asteroid's nickel-iron metal core and its surrounding silicate mantle.1
