This is a listing of sectors that are noted in the Original Series.

Beta sector

Beta sector is the location of a nearby habitable star system at the time of the Celestra mutiny. Mutineers from Celestra originally plan to escape from the Colonial Fleet to the 21st planet of this system (TOS: "Take the Celestra").

Delta sector

Delta sector is the location from where the last wave of Cylon warships approached the Colonial Fleet during refueling operations near the planet Gamoray (TOS: "The Living Legend, Part II").

Hatari sector

Main article: Hatari sector

Hatari sector is the location of Equellus, planet where Apollo crash-lands and later handles a lone Centurion who, commanded by Lacerta, terrorized a town (TOS: "The Lost Warrior").

Omega sector

Omega sector is a region outside the Cyrannus galaxy containing the Delta-class planet Antilla, as well as two other planets.

Previously controlled by human descendants from the Twelve Colonies, the Cylons inevitably took forceful possession of the sector and its planets (TOS: "The Young Lords").

Ontarus sector

Sector Sigma

Sector Sigma is the location of Arcta, itself apparently outside the Cyrannus galaxy (TOS: "The Gun on Ice Planet Zero, Part I").
