- Also includes all bands of system including the close inner system and the far outer system of Oort clouds and orbiting comets or other astrographic objects.
Each orbit should be understood as a generalized band into which an astronomic object such as a planet, belt, or related object may occupy. There are no set distances for each orbit or band, which are determined by the star or stars centered the system.Orbital bands are typically measured in AU or Astronomical Units and the distance between bands is variable.
- 1 to 6 represent the inner worlds of a system.
- Symbolic orbit 6.5 HZ, the Habitable Zone is the Goldilocks area where conventional life has the greatest odds of developing.
- 7 to 12 represent the outer worlds of a system.
- 13 to 144 represent the remote system of Kuiper Belts and Trans-Neptunian Objects.
- 145 to the edge of an astrographic hex or parsec represent the far system where Oort Clouds and the Hill Sphere is located.
Star System Locations
|Type||World Band||Orbit||Estimated Distance||Location/s||Solar Region||Grav. Relationship||Remarks|
|Star||Very Rare||0 (zero)||Center (zero)||Star||Star||Source||Astronomic but not astrographic centerpoint.|
|Inner System||Inner Zone||1 to 6||Up to 42 Light Minutes||HZ Neg||Heliosphere||Significant gravity||Warmer Worlds|
|HZ||Goldilocks Zone||Variable (Orbit 6.5 Symbolically)||Variable||HZ||Heliosphere||Significant gravity||Just right. Goldilocks Zone. Liquid water.|
|Outer System||Outer Zone||7 to 12||Up to 42 Light Hours||HZ Plus||Heliosphere||Significant gravity||Colder worlds.|
|Remote System||Rogue Worlds||13 to 144||Up to 2 Light Weeks||Remote System||Heliosphere to Heliopause to Interstellar Medium||Insignificant gravity||Kuiper Belt. Trans-Neptunian Objects.|
|Far System||Rogue Worlds||Orbit 145 to (3.27 parsecs)||To limits of an area of one Parsec volumetric cube||Far System||Interstellar Medium||Very weak gravity||Oort Cloud/s. Hill Sphere.|
History & Background (Dossier)
The IISS or its counterparts typically only have fairly comprehensive star charts for inner systems (inner zone, HZ and outer zone). Outer systems (remote and far) typically remain very roughly charted or nearly uncharted.
Polystellar star systems with one to six stars can be found within Charted Space. Polystellar star systems with larger numbers of stars are considerably rarer. Polystellar systems are also known as multi-star systems for binaries and multiple-star systems for trinaries or greater.
|Type||# Stars||Rough %||Remarks|
|Monostellar Star System||1||60|| Most common star system.
|Binary Star System||2||30||Common star system.|
|Trinary Star System||3||4 to 5||Uncommon star system.|
|Quaternary Star System||4||2 to 3||Infrequent star system.|
|Quinary Star System||5||1 to 2||Rare.|
|Sextenary Star System||6||N<1||Very rare.|
|Polystellar Star System||7+||N<0.1||Extremely rare.|
