Asteroids in Real Life
Asteroids in Science Fiction
Asteroids often appear in science fiction stories, both in our solar system and in other galaxies. A common idea proposed by scientists and featured in science fiction is the mining of asteroids.
- Isaac Asimov wrote Lucky Starr and the Pirates of the Asteroids.
- Robert A. Heinlein's Rolling Stones features prospectors in the asteroid belt.
- Star Wars: The Empire Strikes Back's Hoth system contained an asteroid belt.
- Star Trek: The Next Generation featured many asteroid belts in various episodes. In one, the Enterprise had to race against time to drag an old, nuclear-powered starship safely through an asteroid belt into the sun because parabolic orbits are unknown in the 24th Century.
- On Stargate, the Goa'uld Anubis tried to wipe out Earth with a planet-killer asteroid primarily composed of naquadah.
