			==Sector==
			Since the vast majority of explored sectors are contained in the sector grids bordering the UFP, the sector grid designation (for instance, "15") is often omitted. In fact, in common usage, it is not unusual to refer to a sector by its last five digits ("sector 07612") or even its last two digits ("sector 12"). Given this numbering system, the last five digits of a sector designation will always be unique for a distance of at least 800 light years in any direction, and the last two digits will always be unique for a distance of at least 80 light years.

			[[File:Sth sectors6 sector.png\|center]]

			==Sector Names==
			Populated or otherwise notable sectors are often referred to by the name of an important star system or planet in the sector, such as the [[Sol Sector]], [[Vulcan Sector]], or [[Bajor Sector]]. Sectors can also be referred to by the name of a well-known stellar phenomena in the region, such as with the [[Mutara Sector]].

			By convention, the Sol Sector is known as Sector 001; this designation has no relation to the overall sector designation system, but merely indicates that this was the first sector explored by [[Earth]]'s space vessels. Nearby sectors similarly retain a traditional sector name based on the order in which they were explored, beginning with [[Alpha Centauri Sector]] (Sector 002).

			===Subsectors===
			For a more exact position, a subsector value can be added to the sector designation or sector name of the described sector. This is generally a 3-, 4-, or 5-digit number assigned to one of a set of equal subdivisions of the sector as measured in parsecs, light-years, or half-light-years. Any greater level of granularity becomes subject to margins of error due to stellar drift and the localized curvature of space-time and so is generally not recommended when specifying an absolute position in stellar cartography.

	Sector grids are divided into 100 SECTOR QUADS of equal volume, which are numbered 00 through 99; these represent the third and fourth digits in the sector designation (prior to the mid-24th Century, sector quads were commonly, though mistakenly, referred to as "quadrants"). Note that closer to the galactic center, sector quads will resemble wedges rather than cubes, and the further from the center of the Galaxy, the large the volume of space contained in each sector quad.

	Each sector quad is divided into 900 or more roughly cubical SECTOR BLOCKS (also known as "Sectors" with a capital "S"). The next three digits in the sector designation (000-999) represent the number of this sector block. Near the UFP, sector blocks are exactly 100 light-years long by approximately 100 light-years wide, with a height of exactly 80 light-years. Sector blocks are laid out in a 9 x 10 x 10 grid instead of a 10 x 10 x 10 grid so that the resulting sectors will be as close to perfect 20-light-year cubes as possible; further out from the galactic core, the width of a sector quad increases from 9 sector blocks to 10 or more.

	==The Sector Designation System==		==The Sector Designation System==
			In stellar cartography, a sector, which is also referred to as a star sector or space sector, is a gridded region within the Milky Way Galaxy. Sectors are composed of an area and volume encompassing several light years and typically contain several star systems. The United Federation of Planets, and as such Starfleet, uses a stellar cartographic system that divides the Galaxy into roughly equal size cubic regions, using these as the formal definition of sectors. The UFP utilizes a hierarchical, position-based naming standard to assign a unique identifier to each of these sectors. This identifier is referred to as the Sector Designation.

			The first digit or letter (0-9, A-Z) in the sector designation refers to the SUBQUADRANT of the galaxy that the sector is located in while the second digit (0-9) refers to the SECTOR ZONE. Together these define the sector grid, the highest level of the hierarchy in the sector designation.

	For more granular charting purposes, the Milky Way Galaxy is further divided into subquadrants and sector zones. The subquadrants are 36 wedge-shaped slices of the galactic disk, each one 50,000 light-years long, 3,600 light-years high, and 8,727 light-years wide at its widest point, representing a 10° arc of the galaxy. The sector zones are a set of 10 concentric circles each 5,000 light-years wide and 3,600 light-years high centered on the galactic core.
