All games feature textured and rendered 3D asteroid models.

Asteroids and comets: Every year, millions of these "stray bullets" streak through the skies, and tons of small meteorites strike our planet. Some 65 million years ago, dinosaurs were wiped off the face of the Earth - in what many believe was the aftermath of a massive cosmic collision. Could something like this happen again? Scientists believe that the impact of an asteroid only a mile wide would be globally catastrophic. Join renowned geologist Eugene Schoemaker and his wife, Carolyn, who together have remapped the heavens with their discoveries of more than 30 comets and hundreds of asteroids.
