Planetoid

Planetoids are the worldlets of a Belt. The Population, Government, and Law Level represent the general level throughout the Belt. TINY

• An astronomical body too small to be considered a planet.
• The Universal Planetary Profile (UPP) uses a world size of 0 to designate an 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.

Planetoid Hulls

Some classes of spacecraft utilize planetoids as hulls: these are noted as being Planetoid or Buffered Planetoid vessels. Denser nickel-iron planetoids are preferred, though some vessels use carbonaceous bodies. Most commonly, a chunk of material of a suitable size, density and internal structure is cut from a larger donor planetoid body. It is then towed to a shipyard and hollowed out, typically through the use of fusion tunneling.

• Only a limited percentage of the volume of a planetoid hull is usable: the remainder forms the structure of the hull. However, this structure affords the vessel integral armor. A Buffered Planetoid retains more of its natural structure, giving it better armor.

The surface of the planetoid vessel may be sculpted. This may be done to give the vessel a more conventional layout, particularly if it is to be carried aboard a larger vessel such as a Carrier or a Fleet Tender. A planetoid ship may also be sculpted to disguise it, making it seem like a natural body.

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.
