Asteroids are objects which can be found at random locations in space.
There are four types of asteroids: Silver, Gold, Platinum and Chem. Each look differently, and have a rather low amount of HP. They can be destroyed by players in order to get a given ore, or will disappear after a given amount of time.
When an Asteroid appears, a message pops out on chat: An asteroid carrying *insert ore name here* was spotted! (You can mark it using your map!)
