The Hoba Meteorite is, by any standards, a most extraordinary object. The largest known single meteorite in the world, it is situated in northern Namibia on the farm Hoba West. Located at 19° 35.5' S, 17° 56.0' E, it lies some 20km west of Grootfontein and 65km south east of the noted mining town of Tsumeb. Amazingly rectangular in shape, with sides 3m x 3m x 1m, it has been calculated to weigh some 61 000kg and is estimated to have landed less than 80 000 years ago (McCorkell , 1968). It is classified as a Group IVB meteorite, a small group of only 13 Ni-Fe meteorites which has recently been shown to be 4 527 ± 29 million years old (Smoliar, 1996).
