The Resolute in the Corvair sector
A sector was an area of space or land framed by an artificial, conventional boundary.
A planetary sector contained a number of solar systems.[2] Sectors were also regional political divisions.[3] The galaxy was divided into a little over 1,000 sectors.[4] Under the rule of the Galactic Empire, individual sectors were placed under the authority of a Moff, or sector governor. Several sectors could be regrouped into an Oversector governed by a Grand Moff.[2]
Specific surface areas of a planetary body could also be partitioned into sectors. During the Clone Wars, the Confederacy of Independent Systems divided their territory on Anaxes into sectors, including Sector One.[5] The Outer Rim world of Batuu transported refuse from Black Spire Outpost to Sector 3263827.[6]
