== Description ([[Specifications]]) ==
 
The average density in the spiral arms is 500 to 650 systems per sector, which works out to 40-50%.  Overall galactic stellar density remains lower than that of individual spiral arms. Galactic stellar densities are affected by astronomic morphology and non-spiral galaxies often hold much different make-ups. A number of other factors may affect galactic stellar density. [[Rift]]s or void areas have a very low density of stars, not a complete absence.

Stellar Density refers to the number of stellar systems contained within a specified volume of space, usually within a Sector.

Please see the following AAB Library Data articles for related information:
Travelling in Charted Space

Description (Specifications)[edit]

The average density in the spiral arms is 500 to 650 systems per sector, which works out to 40-50%. Overall galactic stellar density remains lower than that of individual spiral arms. Galactic stellar densities are affected by astronomic morphology and non-spiral galaxies often hold much different make-ups. A number of other factors may affect galactic stellar density. Rifts or void areas have a very low density of stars, not a complete absence.

Charted Space Sector Density[edit]

This map shows the stellar density of each sector in Charted Space.
