Meteorites are stones from outer space that hit the Earth’s surface.

Most are the debris of asteroids, rocks that orbit the sun.

But could a meteorite land on our head?

Travelling through the atmosphere at 70 000 km/h, most of these bits of rock burn up and become ash.

But thousands of these rocks do hit the Earth each year.

They are difficult to find because many of them fall in the oceans or in uninhabited areas.

But not all! In 1803, a meteorite shower hit the French village of Aigle.
