There are about 22,000 large objects orbiting the Earth, including working and broken satellites and bits of old rocket from past space expeditions. If you include all the equipment dropped by astronauts while floating in space and the debris from colliding satellites down to around 1cm in size, there are about one million bits of space junk in Earth’s orbit.

These numbers are likely to be underestimates. With more satellites and rockets launching each year, collisions with space junk are becoming more likely. Losing a satellite could mean your TV reception is poor or the weather forecast is a bit less reliable. But it could also mean aeroplanes can’t navigate properly and people aren’t made aware of a tornado that’s bearing down towards them.
