The following is a list of unnamed Delta Quadrant sectors.
Sector affected by rogue comet[]
This sector was colonized by several spacefaring civilizations originating from a single planet. Complex organisms on this planet would not have emerged without hydrocarbons supplied by a rogue comet designated Component 37329. In fact, if the comet had never existed, eight thousand civilizations and all life in an area of fifty light years would not have existed either. (VOY: "Year of Hell, Part II")
Sector containing Akritiri[]
This sector contained the inhabited planet Akritiri. It contained no natural sources of trilithium.
In 2373, the Voyager visited this sector. (VOY: "The Chute")
Sector containing Avery system[]
This sector contained the Avery system, which housed a Vidiian base. The sector was visited by USS Voyager in 2371. (VOY: "Faces")
Sector containing Hanon IV[]

Sector containing Ilari[]

Sector containing the Takarian homeworld[]
This sector contained the Takarian homeworld. Six months before the Voyager visited this planet, the Barzan wormhole appeared in this world's system. When the Voyager was in the sector, the starship bombarded an area of subspace instability with verteron particles in a successful effort at bringing the wormhole back to the system. (VOY: "False Profits")

Sector with large plasma drift[]
