<Tr> <Td_colspan="2"> The meteorite in 2014 after becoming a tourist attraction </Td> </Tr> <Tr> <Td_colspan="2"> Related media on Wikimedia Commons </Td> </Tr> <P> The Hoba (/ ˈhoʊbə / HOH - bə) or Hoba West meteorite lies on the farm "Hoba West", not far from Grootfontein, in the Otjozondjupa Region of Namibia . It has been uncovered but, because of its large mass, has never been moved from where it fell . The main mass is estimated at more than 60 tonnes, making it the largest known meteorite (as a single piece) and larger than the 37 - tonne fragment of the Campo del Cielo . It is the most massive naturally occurring piece of iron known on Earth's surface . </P> <P> The Hoba meteorite impact is thought to have occurred more recently than 80,000 years ago . It is inferred that the Earth's atmosphere slowed the object to the point that it impacted the surface at terminal velocity, thereby remaining intact and causing little excavation . Assuming a drag coefficient of about 1.3, the meteor would have been slowed to about 720 miles per hour (0.32 km / s) from its speed on entering the Earth's atmosphere, typically in excess of 10 km / s for similar objects . The meteorite is unusual in that it is flat on both major surfaces, possibly causing it to have skipped across the top of the atmosphere like a flat stone skipping on water . </P>
