The Hoba meteorite
The largest known meteorite that ever hit the planet, it is said to have happened about 80,000 years ago, when it landed in a remote part of Namibia.
It was discovered many centuries later in 1920, when a farmer who worked his fields stumbled over it. It was excavated, but not transported, due to its massive weight of about 60 tons, and can still be visited at the original site. It is believed that it is between 200 and 400 million years old. It is the largest organic piece of iron that man knows, but it also contains traces of substances that are not found on Earth. It measures about three by three meters, with an average thickness of about one meter.
