Sector

Space is incredibly vast which makes mapping it a difficult task. In order to simplify the mapping and positions of star systems and spatial phenomena the entire galaxy is divided up into a series of ‘chunks’.

The first division is the QUADRANT, a wedge-shaped slice of the galactic disk some 50,000 light-years square. In general, galaxies are divided into four equally sized, cubic quadrants, defined by one meridian passing through the galactic core and a second one perpendicular to the first, which also passes through the galactic core. In the case of the Milky Way Galaxy these four quadrants are referred to as the Alpha Quadrant, Beta Quadrant, Gamma Quadrant and Delta Quadrant.

The next division down from the quadrant are SUBQUADRANTS and SECTOR ZONES. The subquadrant is a wedge-shaped slice of the galactic disk 50,000 light years long, 3,600 light-years high and 8,727 light-years wide at its widest point. SECTOR ZONES are a series of concentric circle 5,000 light-years wide and 3,600 light-years high centred on the galactic core.

Each intersection of subquadrant and sector zone is a SECTOR GRID, 5,000 light-years long by 3,600 light-years high. The width of a sector grid depends entirely on its distance from the galactic core; the further from the galactic core the wider the sector grid.

Each sector grid is then divided into 100 SECTOR QUADS of equal volume. Note that closer to the galactic core, sector quads will resemble wedges rather than cubes, and further from the centre of the Galaxy, the larger the volume of space contained in each sector quad.

Each sector quad is then divided into 900 or more roughly cubical SECTOR BLOCKS. Near the UFP in the Alpha Quadrant, and near Pinastri in the Delta Quadrant sector blocks are almost exactly 100 light-years cubed.

Finally we have the SECTOR. In stellar cartography a sector, also referred to as a star sector or space sector, is a cubic region of space, 20 light years across. Sectors are primarily used as the smallest volume of space, or basic unit, in stellar cartography. Most sectors are numbered, and in some cases, named after an important star system in that sector. In Federation nomenclature, the Sol system and Earth are located in Sector 001. Others are named after a key star system, such as the Mutara sector or our very own Pinastri sector.

Typically, a sector contains approximately 40 stars, about two-thirds of which are members of a binary, trinary, or quadrinary system. However, in dense globular star clusters, a sector may contain as many as several thousand stars, and in the void between the galaxy’s spiral arms, sectors may contain no stars at all.

Please note that on all UFS Sector Maps you will see star systems, stations and anomalies denoted by both yellow and orange icons...

  • The yellow icons indicate that the object is non-canon, and was created in official UFS roleplay.
  • The orange icons indicate that the object is canon, and was discovered by the USS Voyager.
