A massive meteorite known as Hoba, weighing around 60 tonnes, has remained in its original location in Namibia since it fell to Earth about 80,000 years ago. Discovered in 1920 by a farmer near Grootfontein, the meteorite was later confirmed as extraterrestrial by the Smithsonian Institution in 1929. It holds the title of the largest known block of meteoritic iron on Earth, with its original mass estimated at 66 tonnes before some natural erosion over time.
The Hoba meteorite's flat shape is believed to have allowed it to bounce through the atmosphere upon entry, which explains why there is no visible impact crater at the site. This unusual shape, combined with its immense weight, made it extremely difficult to move. As a result, the meteorite has never been relocated, despite some natural erosion and scientific sampling over the years.
The meteorite is primarily composed of iron, making up about 82.4% of its mass, with 16.4% nickel and small traces of cobalt. These compositions are typical of iron meteorites, which originate from the cores of differentiated asteroids. The Hoba meteorite serves as a significant reference point for scientists studying celestial objects and their composition.
Since 1955, the site where the Hoba meteorite fell has been designated a national monument, protecting it for both scientific and cultural significance. Today, it continues to attract scientists and tourists alike, offering a rare opportunity to see one of the largest meteorites on Earth in its original location.
