Star Trek Map Of The Alpha & Beta Quadrants

Last Updated: March 3, 2023 25 Comments

The map above is Shakaar’s Alpha/Beta map v3.3; a fan-made creation showing the Alpha and Beta quadrants of the Star Trek universe.

The map shows both major and minor powers that have appeared in the various series over the years.

At the centre is the United Federation of Planets, which borders the major power of the Klingon Empire, Roman Star Empire and the Cardassian Union. More minor powers include the Breen, Ferengi Alliance, Tholian Assembly, Sheliak Corporate and the Gorn Hegemony among many, many others.

The map highlights:

• Principal Systems
• Minor Systems
• Non-Aligned Systems
• Dead Systems
• Government Borders
• Points of Interest
• Navigation Hazards
• Star Clusters
• Stations or Starbases

I know that: a) it’s a bit of fun b) it’s hard to make a 2d map of 3d space and c) there no official maps to go off

But Christ, there’s a lot of stuff on here which makes no sense.

Isn’t gamma haromi 2 supposed to be in the haromi cluster…. Good effort though! S3. E8 I think. The “gatherers”

Why are Ceti Alpha V and Ceti Alpha VI in completely different sectors? I mean, okay, Chekov can be a little dumb sometimes, but that’s one helluva mistake to make.

I agree, several planets said to be in the alpha quadrant are in the beta quadrant and vice versa or not listed at all.

Okay so Xindus by Vulcan…. kys I’m not even gona bother looking further don’t make a map if you don’t know what your talking about

Romulons should have Dyson sphere (at least at Romulus and Remus). Their ship tech is based on creating black holes which will give a ship a reactor core with a life of a handful of years BUT it’s just like an inefficient battery because it takes way more energy to initially create it then it will give off over its life BUT it’s portable. Sure beats light sails if your depending on home system energy and way more flexible too. This was their tech wheelhouse, and was their interstellar travel energy source instead of antimatter. It makes total sense for them to have harnessed the majority of their native suns energy to create reactor cores wherever they needed a portable energy that couldn’t tap into the system wide grid.

A few questions… 1) Why are there several Indus VIII on the map?, 2) I do not see the First Federation on this map — they should be near the Ferengi!, 3) Where is the Kelvin planet? (The planet colonized by the Kelvins from “By Any Other Name”), 4) Maybe I’m wrong, but I do not see the Dyson Sphere that TNG crew ran into?

Not your fault, I know;

Vulcan is “Supposed” to be “A little over sixteen” light years from earth. Yet the map has it at around 1000. That’s one of my biggest gripes about Star Trek (I absolutely love Star Trek, don’t get me wrong). Distances and travel times are so inconsistent and unrealistic based on the documented scales, maps, etc.

March 14, 2020 at 11:46 pm

Did you mean Starbase 375 instead of 395? As in the starbase from S6 of DS9 after the Dominion took over the station?

I love this map, especially how you have the Hydran Kingdom, the Lyran Star Empire and the Kzinti Hegemony are listed (where is the Interstellar Concordium?). I have one small nit-pick to make and that is you have two systems named “Nelvana III”. They’re both in the upspin Beta quadrant but one is in the Romulan Neutral Zone and the other is further upspin and outward (left). I think that you might consider making most of the empty space that is coreward of Klingon and Romulan space into the ISC. They were referred to as being a Galactic Superpower residing on the far side of both those Empires (so, coreward).

I dont understand how this can be called a map of the star trek galaxy when there isnt even a spot or indication of where earth is. Who makes a map without earth when you have a series where its location is based on earth. In the series they refer to Earth as Earth. Yet the closes thing to it is on the map is Volcan. Y not add Earth as well? If there is an alternative name how come it’s never mentioned in the shows and a secret for fans?

Brandon says

August 15, 2020 at 4:14 pm

Earth is 100 percent there. It’s Sol. It’s a common alternate name for our star system and has been used in Trek.

February 8, 2021 at 3:26 pm

Sol system. The Greek word for sun. Follow the bold line and look for the team Terran and Vulcan sectors. Sol is on the 4 corners there

Star Trek : Map

The Tholian Assembly is the state of the non-humanoid Tholians which signed a nonaggression pact with the Dominion, but remained in a neutral position until the end of the war. Contact with the Tholians happens rarely.

2.1.1 The subdivision of the Galaxy

While in our time, we haven't ventured deep enough into space to need other systems for the exact determination of positions within our incredibly large galaxy than the equatorial and galactic coordinate systems, in the world of Star Trek, in which the interstellar navigation is the basis of trade, politics and the everyday life of billions of people, a further subdivision of space is used, beside the much two large  division into "galaxies" and the much two small division into "planetary systems" - the subdivision into quadrants and sectors. These two terms, whose meaning was quite contradictious at the beginning, but has been exactly fixed in the meantime, have become a basic element of the space navigation shown in  Star Trek through the years, since with the sector and quadrant system, a certain place can be quite precisely localized, without using a complicated coordinate system.

1. The four quadrants

Already in the era of Classic Trek, the expression "quadrant" was used for the exact determination of positions in the Star Trek universe. However, this cartographic term which literally refers to "a quarter" was used for completely different three-dimensional volumes at that time: sometimes a quadrant indeed corresponded to a quarter of the galaxy, but all too often it also denoted considerably smaller regions. In this connotation, the size of a quadrant rather corresponded to the size of a sector, like the designation "quadrant 904" in [TOS] The Squire of Gothos indicates. Up to the beginning of The Next Generation and also in the first movies the "quadrant" wasn't defined unambiguously and was used contradictorily. Finally in Star Trek VI, the current - and correct - quadrant system was introduced, according to which "the galaxy is subdivided into 4 quadrants, from which each forms a 90 degrees piece of cake, viewing the galaxy from the top or the bottom" (Star Trek Encyclopedia). An insider information on this movie even implies that the system was mainly introduced to justify Captain Sulu's claim that "he is in the Beta quadrant and currently the only Star Fleet ship in the quadrant."

Even a subspace transmission (warp 9.9999 with amplification) covers this distance in more than three    months. Consequently, only the fact that Earth, the Federation and most of the other empires are located at the frontier between Alpha and Beta quadrant makes it possible that we hear something about other quadrants at all, and it isn't surprising that the two remaining quadrants - Gamma and Delta - were not  explored until the era of DS9 and Voyager started, and then only with "tricks" like wormholes and intergalactic displacement waves.

2. The sectors

In contrast to the quadrants, space sectors, that are mentioned in nearly every episode (remember sector 001 - the solar system), are an astronomically small division of the galaxy and therefore more useful for the exact determination of positions in Star Fleet's everyday life - what explains their often use (although, however, in the recent seasons of Voyager and DS9 the Alpha Quadrant was mentioned in every second episode). Because the dimensions of a sector are, in contrast to the quadrants, not important for the episodes and this subdivision was always used for space regions of small scale, it isn't astonishing that the official definition was not determined "first hand" in a episode or movie (not even as background information), but in an official documentation.

At any rate, a sector is apparently not a natural, but a artificial, systematic subdivision of the galaxy into smaller space regions, what is also supported by the Encyclopedia, which suggests that "a typical sector in Federation space contains 6-10 planetary systems, although there are many more in the sectors near the Galactic core." Therefore, Sector 001 should not only contain the solar system, but also e.g. the Wolf and Alpha Centauri systems.

Just as the quadrants, also the sectors have some irregularities in their designation, but that's acceptable in this case, because of the sector numbering system of the Federation, we only know the starting point (sector 001), but not the direction of the numbering, and the situation of the numbered sectors introduced in different episodes towards each other is unknown. However, it is very likely that in view of the centuries of space exploration and already different designation systems today, the system of the Federation is contradictious itself and the sectors are numbered more or less arbitrarily. It is also possible that the sector numbers, like the registry numbers, were assigned to newly discovered space regions at entirely different locations in space with increasing sequence, and the sector system accordingly has a chronological order.

The Star Trek Encyclopedia suggests that "some sectors kept their old designations from earlier cartographing systems the same way as we use today both the older Messier and the newer NGC numbering system." In fact, some sectors apparently haven't a number at all (like the Igo Sector and the Bajoran Sector); they were named after the dominating planetary system or most important star in the sector.

2.1.2 The political division of the Galaxy

Already the mere space explored by humanity - about 5000 ly on both sides of the Alpha/Beta Quadrant border, at which Earth is located, there are six closely adjoined interstellar alliances and empires - Federation, Romulan Star Empire, Klingon Empire, Cardassian Union, Breen Confederacy, the Tholian Assembly and a dozen other important powers such as the Ferengi, Trill, Talarians, Tzenkethi and Gorn. However, actually solely the United Federation of Planets with 150+ member planets, numerous Federation protectorates and hundreds of colonized planets, which are scattered over 8000 ly and distributed to several agglomeration areas ("cores"), is large enough to be visible on an overview map without exaggerated dimensions. Beside the Federation, the sole super power in the (known) lower part of the Milky Way, however, there are more comparably large or even larger powers in the upper half: the Dominion in the Gamma Quadrant, which takes up a whole part of the Sagittarius arm of the Milky Way, and the Borg Collective, which core region has a perhaps five times as large volume than the Federation has, but whose sphere of influence extends over the half Delta and Beta Quadrant. There are still other powers in the Galaxy, but which do not owe their large territories to their political status (like the Federation as a loose, not necessarily spatially joined interplanetary alliance) or their superiority to other species in numbers or technology (like the Borg or the Dominion), but to other factors, which effect the extension of their empires. For example, the Krenim belong(ed) to the dominating super powers in the Delta Quadrant with almost a thousand planetary systems solely due to alterations of the time line, which enlarged their empire and finally made it smaller again. On the other hand, the Hirogen dominate a larger area of space despite their slow ships because of the nomadic way of life which is typical for them - they restlessly travel around to hunt their prey. The Turei inhabit a larger part of the lower Delta Quadrant, because they have access to the sophisticated subspace corridor system of the Vaadwaur. In the end, most peoples have too little influence on other empires or a too less established territory to be called a super power, so that the number of interstellar important alliances is very limited. Finally, the exact political subdivision of the Galaxy remains unknown, because our knowledge is sketchy at best. Only some small parts of the Alpha, Beta and Delta quadrants are known, in which nonetheless the territories of more than a dozen powers are located. The Gamma Quadrant could be explored merely four years, until the Dominion - the sole power known in this quadrant - prevented this. Consequently, there is enough space in the Milky Way for hundreds of interstellar alliances and empires, which could be discovered already with the next deep space mission - the Cytherians, which apparently populate a huge part of the galactic center, are only one example.

After this summarizing introduction in the general subdivision of the Milky Way and the political situation in the Galaxy, now the time has come to immerse in the Star Trek Galaxy and to examine the most important planetary alliances and empires, their location, structure, formation and development more elaborately, starting with the United Federation of Planets.

The Sol Sector

Sector 001 , also known as the Sol Sector or the Terran sector , was a region of space in the Alpha and Beta Quadrants . This was the central sector of the United Federation of Planets in which the Sol system was located. It bordered the Omicron , Yadalla , Antares , Vulcan , and Muratas sectors . ( TNG : " Conspiracy ", " The Best of Both Worlds "; DS9 : " Emissary "; VOY : " Hope and Fear ", " Endgame "; Star Trek: Enterprise ; PRO : " Starstruck ")

History [ ]

From 2161 to the 31st century , Federation Headquarters and Starfleet Headquarters were located in this sector. After the 31st century , when Earth declared its independence from the Federation, the two headquarters were relocated to another sector where they jointly shared a space station . ( ENT : " Zero Hour "; DIS : " People of Earth ", " Die Trying "; Star Trek: Insurrection )

Data examined the starbase ops status of the Sol Sector in late 2364 , finding proof for a conspiracy among the highest ranks of Starfleet Command . ( TNG : " Conspiracy " okudagram )

In 2368 , in his final year at the Starfleet Medical Academy , Julian Bashir was the captain of the racquetball team. They took the sector championships this year. ( DS9 : " Rivals ")

In 2369 , this sector was named on the chart " Sector Ipai Relay Log – Relay Message Flow 1293" in Relay Station 47 Ops. The USS Zhukov was in this sector around the same time that the USS Enterprise -D visited Relay Station 47 . ( TNG : " Aquiel " production art )

In 2371 , a microscopic singularity passed through Sector 001 and exploded. This created the conditions for an accident that sent Benjamin Sisko , Jadzia Dax , and Julian Bashir back in time to the year 2024 . ( DS9 : " Past Tense, Part I ")

In 2372 , Bashir gave Nog a PADD containing the guidebook A Cadet's Guide to Sector 001 Earth for life on Earth as a going-away present . ( DS9 : " Little Green Men ")

The Battle of Sector 001 between the Federation and the Borg occurred in this sector in 2373 . ( Star Trek: First Contact ).

In the 2380s , a section of the holographic map of the Alpha and Beta Quadrants , displayed to the former prisoners of Tars Lamora aboard the USS Protostar , was labeled as the Terran sector. ( PRO : " Starstruck ")

In an alternate timeline caused by the death of Gabriel Bell in 2024 , the USS Defiant did not detect Starfleet activity in this sector in 2371 . ( DS9 : " Past Tense, Part I ")

In the alternate 2259 , this sector, located at Level 3-B , was labeled on a map of the Alpha Quadrant. Four trade lines radiated from a white pentagon in this sector. The sector was being scanned for activity. This map was in a collection of graphics and video media that were seen on a powerwall in the offices of Admirals Christopher Pike and Alexander Marcus at Starfleet Headquarters . ( Star Trek Into Darkness )

The meaning of the pentagon was not defined on the map.

As the result of the two-dimensional nature of the map, it was not possible to know the region's location in relation to the Klingon Empire . The map was visible in the video " Star Trek: Into Darkness – User Interface VFX at vimeo.com. [1]

After 57 Years, Star Trek Settles the Truth About Trelane's Godlike Species

I’m glad voyager’s tom and b’elanna are no longer star trek's only successful romance, star trek isn’t supposed to have money: what is latinum.

Warning: contains spoilers for Star Trek: Defiant #17!

After 58 years, Star Trek reveals why it uses quadrants, despite the universe being infinite. The galaxy is a vast place, much too big for one starship to travel in a lifetime. The sheer size of the galaxy has forced the Federation and other galactic powers to devise a system of “quadrants” to divide it up, and now Star Trek: Defiant #17 reveals how and why it was created.

Thus, to allow computers to crunch the enormous amounts of data needed to navigate a starship, galactic powers, including the Federation, created a system of quadrants.

Star Trek: Defiant #17 is written by Christopher Cantwell and drawn by Angel Unzueta. Chief O’Brien, now a lecturer at Starfleet Academy, is lecturing on automata theory. O’Brien quizzes the students on the theory’s limits, stating that it breaks down when confronted with infinity. The galaxy is large and full of unpredictable elements. Thus, to allow computers to crunch the enormous amounts of data needed to navigate a starship, galactic powers, including the Federation, created a system of quadrants.

O’Brien concludes by stating it is a matter of acknowledging limitations and devising workarounds for them.

Star Trek's Quadrant System's Origins Have Never Been Explained--Until Now

The star trek universe is vast.

The quadrant system is integral to the Star Trek universe, but it has not always been used consistently. In early episodes of the classic Star Trek series, the terms “quadrant” and “sector” were used in a seemingly interchangeable fashion. As Star Trek lore solidified, a consistent system was created based on four different quadrants: Alpha, Beta, Delta, and Gamma. Quadrants are massive: in Star Trek: Voyager’s series premiere, the ship was hurled from the Alpha to the Delta. It was estimated it would take nearly 80 years for Voyager to get home–at maximum warp.

As a way to make the vast quadrants even more manageable, the Federation and other galactic powers divided them up into sectors, with Earth at the center of Sector 001. Creating sectors within quadrants allowed starship computers to run their calculations even more efficiently. Not only is it the perfect example of a workaround for the limitations of automata theory as explained by Chief O’Brien , but a testament to the creativity inherent in all species. Critics charge the system is very Earth and human-centric, but the quadrant system is still a useful tool.

Star Trek Producers Should Adopt This Origin for the Quadrant System

The origin is real-world plausible.

The origin of the quadrant system is a neat bit of world-building within the Star Trek universe, explaining a key piece of lore. Since this revelation occurred in the comics, it is, per the policy of Paramount, non-canon. However, certain elements from licensed Star Trek media, such as novels, have made it into the canon, such as Sulu and Uhura’s first names. The origin of the quadrants, as laid out in Star Trek: Defiant #17 are grounded in real-world scientific theory, and future Star Trek showrunners could easily adapt this theory to the screen.

Star Trek: Defiant #17 is on sale now from IDW Publishing!
