Asteroids are mostly, block like rocks that are in space. They can vary in a few colors, varying from grey, to brown. They are also randomly generated, so each time a system is loaded in, their positioning is not always the same as before. Asteroids are of course, commonly found within Asteroid Belts, in the corners of each System in the game, where they can be found in large amounts. Asteroids can be mined for Ru, with the Excavator.
