In 1920, a farmer ploughing near Grootfontein in Namibia struck a buried slab of iron weighing roughly 60 tonnes. It proved to be Hoba, the largest intact meteorite ever found, and it has never been moved from where it landed—probably less than 80,000 years ago. No crater survives around it; its broad, flat shape may have slowed its descent until it struck more like a colossal dropped anvil than a cosmic projectile.
