A World or Planet is an astronomical body located in the void, usually orbiting a star.
- The IISS also uses these astrographic terms near interchangeably.
Library Data Referral Tree[edit]
Please refer to the following AAB Library Data for more information:
- Charted Space Observation
Description (Specifications)[edit]
The term world refers to the various bodies that are contained in a stellar system; it encompasses planets, satellites, and asteroid belts. For example, the single most important world in a system may not be a planet; it could be a satellite of a gas giant, or it could be a planetoid within an asteroid belt. [1]
Planets possess a vast variety of identifying characteristics and can be categorized in many different ways. Some of the most common ways include: size, composition, exotic, and special natures.
Basic Planetary Types (Composition)[edit]
- Borean World (Ice Ball)
- Jovian World (Gas Ball)
- Terrestrial World (Rock or Iron Ball)
Type | Nickname | Composition | Remarks |
---|---|---|---|
Terrestrial World: Silicate world | Ice Ball | Icy or rocky world. Ice or light silicate rock. | Density of 1.3 to 3.0 gm/cc^3, Borean World. |
Terrestrial World: Low Iron world | Rock Ball | Rocky world. Heavy silicate rock, light metals. | Density of 3.1 to 4.5 gm/cc^3 |
Terrestrial World: Medium Iron world | Rock Ball | Rocky world. Moderate mixing of iron and denser metals with silicate rock and lighter metals. | Density of 4.6 to 6.0 gm/cc^3. Terra is a Medium Iron world. |
Terrestrial World: High Iron world | Iron Ball | Metal world. Mostly iron and denser metals with a few silicate rocks. | Density of 6.1 to 7.0 gm/cc^3 |
Terrestrial World: Metallic world | Iron Ball | Metal world. Entirely iron and other dense metals. | Density over 7.1 gm/cc^3 |
Jovian World | Gas Ball | Mostly gases & some solids. | Typically Gas Giants. Technically means huge world. Satellites of gas giants are known to have moons that can be habitable to conventional life. Jupiter is a gas giant. |

History & Background (Dossier)[edit]
Scientist argue about a variety of celestial objects and are constantly defining and redefining what is and isn't a planet:
- Planetary-Mass Object (PMO)
- Planemo
- Planetary body
- Dwarf planet
- Protoplanet
- Small Solar System Body (SSSB) [Minor planet]
The Solomani are particularly contentious in this area and the IAU (International Astronomical Union) definition of planet has fluctuated many times over the millennia.

Bioplanetological Sciences[edit]
Science | Actor Scientist |
Remarks |
---|---|---|
Xenobiology | Exobiologist | The study of creatures, pre-sophonts, or lower intelligent lifeforms.
|
Sophontology | Sophontologist | The study of sophonts or intelligent lifeforms. Includes Proto-sophonts |
Terraforming | Terraformer | A planetary engineering process which, over many years, converts a hostile world (Inhospitable World) into a livable one (Hospitable World). |
Planet vs. World[edit]
What are the technical differences between the terms planet and world? In common usage, they are used interchangeably, but how do IISS scouts use the terms?
Term | Remarks |
---|---|
Planet | Denotes an astronomic and astrographic meaning and applies to all of the bodies in a system. |
World | Denotes a socioeconomic and sophontilogical meaning and mostly applies to those bodies with sophont populations, usually main worlds or satellite worlds. |
