Could a meteorite be as big as a bus?
Yes! The biggest meteorite ever found, Hoba in Namibia, is about the size of a small car and weighs around 60 tonnes, heavier than five buses full of people.
Most meteorites are small enough to hold in your hand, but some are giants.
The biggest single meteorite ever found is called Hoba. It lies on a farm in Namibia, in southern Africa, exactly where it landed, perhaps around 80,000 years ago. It is a slab of iron and nickel about 2.7 metres long and almost a metre thick, and it weighs about 60 tonnes, as much as about ten elephants. It is so heavy that nobody has ever moved it, so visitors go to see it instead.
Other huge meteorites include Cape York, found in Greenland, whose biggest piece weighs about 31 tonnes and is in a museum in New York, and pieces of Campo del Cielo in Argentina, some weighing around 30 tonnes or more. All the really big ones are iron meteorites. Stony meteorites tend to break apart in the air, but iron ones are strong enough to survive.
The space rocks that make giant craters are even bigger, perhaps tens of metres to kilometres across, but they are going so fast that they mostly melt or vaporise when they hit, so only small pieces are left to find.
