You don't expect to find a chunk of meteorite on your driveway.
Several incredibly rare pieces of this space rock have been found in Gloucestershire in the UK.
They were recovered after a fireball meteor lit up the night sky over the UK and Northern Europe 10 days ago.
Richard Greenwood is a planetary scientist from the Open University. He was the first person on the scene to identify the meteorite pieces.
He spoke to Corin Dann.
