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).
Description (Specifications)
Planetary density and size are two primary factors hen determining a planet's gravity.
Planetary Size Data
The following table outlines the UWP codes for the size of a body:
Planetary Size Code Description Diameter (Km) Expected
GravityRemarks 0 Asteroid/Planetary Belt (...around a star)
Multiple < 200 Microgravity Tiny World R Asteroid/Planetary Ring (...around a world)
Multiple < 1 Microgravity Tiny World D Debris 1+ < 200 Microgravity Tiny World S Very Small 200-799 (400 km, 0.02g - 0.03g) Small World 1 Small 800-2399 (1,600 km, 0.05g - 0.09g) Small World 2 Small (e.g. Luna) 2,400-3,999 (3,200 km, 0.10g - 0.17g) Small World 3 Small (e.g. Mercury) 4,000-5,599 (4,800 km, 0.24g - 0.34g) Meso World 4 Small (e.g. Mars) 5,600-7,199 (6,400 km, 0.32g - 0.46g) Meso World 5 Medium 7,200-8,799 (8,000 km, 0.40g - 0.57g) Meso World 6 Medium 8,800-10,399 (9,600 km, 0.60g - 0.81g) Macro World 7 Medium 10,400-11,999 (11,200 km, 0.70g - 0.94g) Macro World 8 Large (e.g. Venus/Terra) 12,000-13,599 (12,800 km, 0.80g - 1.08g) Macro World 9 Large 13,600-15,199 (14,400 km, 1.03g - 1.33g) Big World A Large 15,200-16,799 (16,000 km, 1.14g - 1.48g) Big World B Huge 16,800+ Macrogravity Big World SGG Small Gas Giant (no futher codes) 40,000-120,000 Macrogravity Gas Giant LGG Large Gas Giant (no further codes) 120,000-240,000+ Macrogravity 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.
