Planetoid
An astronomical body too small to be considered a planet.
- The Universal Planetary Profile (UPP) uses a world size of 0 to designate a asteroid belt.
- Please also see ringworld, rosette, sphereworld.
Description / Specifications
Generally any object less than 500 kilometers in diameter is considered to be a planetoid, although it may be called a moon if it is a satellite of a planet.
- For the purposes of distinction, the term asteroid belt is used to describe a planetoid belt which forms the main "world" in a stellar system.
Planetary Characteristics
The term planetoid belt refers to a belt of minor planets when another belt or world is the main world in a system.
- Asteroid and planetoid belts typically hold between 1,000 and 10,000 asteroids or planetoids each.

History & Background / Dossier
Planetoids generally cluster together in planetoid belts which encircle a star.
- These belts have a number of possible origins. For example, a planet may have failed to coalesce during the formation of its star system. It is also possible that a planet has been torn apart by tidal forces, leaving a path of scattered debris.
Final War Artifacts
Finally, many belts in and around the Third Imperium were formed by "planet-buster" weapons used in the Final War. These weapons used technologies with capabilities far beyond anything that TL-15 science can produce. It is widely thought that highly advanced antimatter weapons might have been one of those technologies.
