Asteroid - Asteroids, Meteors And Impacts
| Season 1

| SBS
Between the orbits of Mars and Jupiter is the asteroid belt, a swarm of rocky bodies. Every so often, perturbed perhaps by the gravitational tug of Jupiter, asteroids collide and tumble towards the Sun. If they pass Mars, they can threaten Earth. 65 million years ago an asteroid impact most probably killed the dinosaurs. That threat from space continues. How do we protect our planet? To get to know our enemy, robot spacecraft visit asteroids.
