Sector

Sectors are the largest subsections of the galaxy. Each sector is a constant 4,166.67 lightyears long, but each sector ⎯ depending on which ring they belong to ⎯ varies in width ranging from 312.15 lightyears, towards the core, and 3,541.1 lightyears, towards the galaxy's rim.

Sectors are split up into 13 rings, labeled A-M, each spaced 4,166.67 lightyears from the last, radiating away from the galactic center. Each ring is split up into 112 wedges.
