The Truth About Meteors: A Horizon Special

Episode 7 of 18

Professor Iain Stewart explains what meteorites and asteroids are, where they come from, the danger they pose and the role they have played in Earth's history.

On a bright, cold morning on 15 February 2013, a meteorite ripped across the skies above the Ural mountains in Russia, disintegrating into three pieces and exploding with the force of 20 Hiroshimas. It was a stark reminder that the Earth's journey through space is fraught with danger. A day later, another much larger 143,000-tonne asteroid passed within just 17,000 miles of the Earth.

Presented by Professor Iain Stewart, this film explores what meteorites and asteroids are, where they come from, the danger they pose and the role they have played in Earth's history.
