World is an Asterioid Belt or Planetoid Belt, consisting of 1,000 and 10,000 asteroids or planetoids each. Asteroid belt is the belt when it is the main world of a system. Planetoid belt is another belt or when another world is the main world.

| SGG
|
World is 40,000-120,000 km in diameter.
- Macrogravity: 2.01+ G.
- This is a small Gas Giant. Ships, especially those with low thrust, usually orbit it (to skim fuel, hide, or whatever other job they have.)
- Vessels with only 1G of thrust should not skim fuel from this planet
- Standard surveys suggest there is nothing to land on.
