From Traveller Wiki - Science-Fiction Adventure in the Far future
Worlds are classified according to their physical size (Planetary Size).
- Only Mainworlds (worlds or planets) of interest are recorded.
- e.g. Gas Giants are simply classified as Small (SGG) or Large (LGG).
The following table outlines the UWP codes for the size of a body:
Planetary Size Code Description Diameter (Km) Remarks 0 Asteroid/Planetary Belt
(...around a star)
Multiple < 200 Tiny World R Asteroid/Planetary Ring
(...around a world)
Multiple < 1 Tiny World D Debris 1+ < 200 Tiny World S Very Small 200-799 Small World 1 Small 800-2399 Small World 2 Small (e.g. Luna) 2,400-3,999 Small World 3 Small (e.g. Mercury) 4,000-5,599 Meso World 4 Small (e.g. Mars) 5,600-7,199 Meso World 5 Medium 7,200-8,799 Meso World 6 Medium 8,800-10,399 Macro World 7 Medium 10,400-11,999 Macro World 8 Large (e.g. Venus/Terra) 12,000-13,599 Macro World 9 Large 13,600-15,199 Big World A Large 15,200-16,799 Big World B Huge 16,800+ Big World SGG Small Gas Giant (no futher codes) 40,000-120,000 Gas Giant LGG Large Gas Giant (no further codes) 120,000-240,000+ Gas Giant
- Note that the size code D ( Debris ) is non-standard. It is included to cover such cases as Comet Mid-Rift (Deneb 3234), which are less than 200Km, but not part of an asteroid belt, yet important enough to have mention.
