Theron Classification System
5/11/2008 Version 1.63

Information:
The Theron System was pioneered by a day four* Arkian scientist working in the newly explored cluster Hi Theron in the Haba year 4224. The system officially replaced the older Evren System by Imperial statute #2213120010-3 affirmed by the First Court on 2,2,13,12,0,21 item 11.

*Day four scientists include astronomers, navigators, calendar keepers, astrologers (It hurts, I know) etc. - any discipline that involves studying stars, planets, moons and other celestial objects or their cycles is considered a fourth day science.

The Theron Classification system in managed by the Arkian Department of Stellar Cartography - Se'toina Central on Arkooinath 1046610.

Syntax: SID=sector ID; ST=star type
Abbr.: #C=number of clusters; C#=cluster number;
#S=number of stars; S#=system number;
#P=number of planets; P#=planet number;
#M=number of moons; M#=moon number;
PC=planet class; AC=anomaly class
Sector: (sector number)L(#C)
Cluster: [SID]-(C#)K(#S)
Star: [SID]K(#S)(ST A-I)(C#)-(S#)P(#P)
Planet: [SID]K(#S)(ST)(C#)-(S#)N(P#)/(PC)S(#M)
Moon: [SID]K(#S)(ST)(C#)-(S#)N(P#)/(PC)R(M#)
Outlier star: [SID]Q(ST)(S#)P(#P)
Outlier planet: [SID]Q(ST)(S#)N(P#)/(PC)S(#M)
Anomaly: [SID]K(#S)M(C#)-(anomaly #)/(AC)
Black hole: [SID]K(#S)J(C#)-(anomaly #)
Variable Planet: [SID]K(#S)(ST)(C#)-(S#)N(P#)/MS(#M)

Notes:
Binary systems may name individual stars by adding
A lower case letter after the star number. The star is
numbered by its rank of absolute luminosity.

Definitions:

Planet:
Any object with a true mass below the limiting mass for thermonuclear fusion of deuterium and has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round shape) is a "planet" no matter how it is formed.

Dwarf planet: Object that meets the above criteria, but does not clear its neighborhood of debris.

Titan planet: Object that meets the above criteria and is large enough to capture objects large enough to capture planetary (as described above) objects as moons.

Rogue planet: Object that meets the above criteria, but does not orbit another object.

Variable Planet: Object that meets the above criteria and has wildly variable surface conditions.

Satellite:
Any object orbiting a non-solar body is a "satellite".
Moon: A satellite orbiting a planet.

Minor body:
Any object that is smaller than a planet is a minor body or "planetoid".
Asteroid: A planetoid larger than 10km in diameter.
Meteoroid: A planetoid less than 10km in diameter.
Comet: Any planetoid exhibiting a coma.

Keep on the lookout for the next big version update, which may affect the way that clusters are determined and numbered.
