Sophonts have been exploring the stars for millennia.

  • Astronomy is the name of the science of studying the stars.

Description / Specifications[edit]

The System Densities table describes the density of Star Systems in the different areas of known space.

Stellar System Density Table[edit]

Stellar Density Table (…by mainworlds AKA world-systems) IISS T5SS Protocols (v.1720.21c / pg. 421)
ZT Zone Type (ZT) Designation  % Subsector Range Sector Average Sector Range Remarks
AV Absolute Void Empty 0% 0 worlds 0 worlds 0 worlds Absolutely empty of significant planetary objects.
EG Extra-Galactic Very Sparse 1-2% 1 world 6 worlds 1 to 37 worlds Rogue planets and other galactic ejecta.
  • The stars are so few in this zone and it is nigh impossible for low capability FTL engines to traverse Extra-Galactic Space.
  • Extra-Galactic Space is practically impossible for lower technology civilizations to traverse.
IntG Rift Sparse 3-6% 2 to 5 worlds 38 worlds 38 to 215 worlds Rifts are the mostly empty places within a galaxy structure.
  • The stars are very few in this zone and it is almost impossible for low capability FTL engines to make their way around.
  • Rifts are significant barriers to interstellar travel for lower technology civilizations.
IntG Spare Very Low 7-32% 6 to 25 worlds 216 worlds 216 to 419 worlds Spare zones begin to form aggregate planetary masses.
  • The stars are very spare in this zone and it is very difficult for low capability FTL engines to make their way around.
IntG Scattered Low 33-49% 26 to 39 worlds 420 worlds 420 to 639 worlds Scattered zones contain significant planets and have significant potential for conventional life.
  • The stars are scattered in this zone and it is difficult for low capability FTL engines to make their way around.
IntG Standard Average 50-65% 40 to 52 worlds 640 worlds 640 to 839 worlds Standard zones contain a goodly number of planets and have good potential for conventional life.
  • The stars are moderately dense in this zone and it is a little challenging for low capability FTL engines to make their way around.
IntG Dense High 66-82% 53 to 65 worlds 840 worlds 840 to 1,059 worlds Dense zones contain a lot of planets and have very good potential for conventional life.
  • The stars are dense in this zone and it not difficult for low capability FTL engines to make their way around.
IntG Cluster Very High 83-90% 66 to 72 worlds 1,060 worlds 1,060 to 1,169 worlds Cluster zones contain many planets and have great potential for conventional life.
  • The stars are very dense in this zone and it is easy for low capability FTL engines to make their way around.
IntG Core Dense 91-100% 73 to 80 worlds 1,170 worlds 1,170 to 1,280 worlds Core zones contain many, many planets, but the density and radiation make conventional life very difficult.
  • The stars are so dense in this zone that even the least capable FTL engines can easily make their way around.
IntG Full Very Dense 100% 80 worlds 1,280 worlds 1,280 worlds The maximum number of Main World star systems possible within the specified area.
  • IntG = Intragalactic Space.
