Sector Classification Guide |

A sector zone is a concentric circle, 5,000 light years wide and 3,600 light years high. There are 10 sector zones in the Milky Way Galaxy. The second digit of a sector's designation is its sector zone. |

A subquadrant is a wedge-shaped slice of the galactic disk. There are a total of 36 different subquadrants in the Milky Way Galaxy. Each one is 50,000 light years long, 3,600 light years high, and 8,727 light years across at its widest point. The first digit of a sector's designation is its subquadrant. |

The point where a subquadrant and a sector zone converge is called a sector grid. This division of space is approximately 5,000x5,000x3,600 light years. The sector grid designation for the Sol and Kilka Sectors, and most other Federation worlds is 15 (subquadrant 1, sector zone 5) A sector grid is further divided into 100 sector quads of equal volume. They are numbered 00 through 99, and represent the third and fourth digits of a sector's designation. |

Each sector quad is even FURTHER divided into something called a sector block. On average, sector blocks are about 100x100x100 light years in size. There are 1,000 sector blocks in every sector quad, numbered from 000 to 999. These digits compose the next three digits of a sector designation. |

of 20x20x20 light years in volume. Labeled 00

through 99, they make up the final two digits in a

sector's designation. A typical sector in

Federation space contains between six and ten

star systems.

are frequently omitted in the designation, as most of

explored space lies within Grid 15 Quad 02.

Sector designations (the Kilka Sector is thusly known as Sector

17327). Given this numbering system, the last five digits of a

sector designation are unique at a distance of at least 800 light

years, and the last two digits will always be unique for a

distance of 80 light years. Of course, many sectors are

commonly referred to by the name of a dominant star within

its boundaries, eliminating confusion even more.
