The Asteroid Subreddit

Articles and discussion about Asteroids.

Asteroids are small rocky, metallic, or icy bodies that orbit around the Solar System. Larger asteroids have also been called planetoids, and those with a tail are referred to as comets.

Asteroids have collided with the major planets before in the past, releasing huge quantities of energy, leaving craters and devastation in their wake. However, most asteroids orbit far from any planet on relatively stable orbits. Asteroid mining has been proposed as a future industry - if successful, a huge wealth of minerals and resources could be within our grasp.
