This article is about the rock.  For a list of asteroids, see Category: Asteroids.

Asteroids are huge floating space rocks which, although relatively uncommon in the vast emptiness of space, still pose a menace to traveling spaceships throughout the universe.  Often gravity pulls them together into large groups called asteroid fields.  Many contain and are mined for gold, copper, illyrium, and/or other valuable elements.

Asteroids occasionally crash into planets and cause minor inconveniences such as property damage and mass extinctions.
