Federation members

In 2373, the United Federation of Planets consisted of at least 150 member planets, spread over 8,000 light years. (Star Trek: First Contact)

We may assume, that the admission policy of the Federation regards governments and/or planets, and not whole species. In practice, a planet has to be unified under one joint government until it can apply for Federation-membership. However, there are exclusions like the Kes, thus rendering a single planetary government preferable but not obligatory.

Founding members Edit

The United Federation of Planets was founded in 2161 by the following members:

According to "It's Federation Day!", a newspaper article created as background material for Star Trek Generations, the independent Alpha Centauri colony was another Federation founding member.

Protectorates Edit

Evora Homeworld: Homeworld of the Evora. (Star Trek: Insurrection)

Haven was said to have a treaty with the Federation which required Starfleet to protect it, and thus may have been an official protectorate.

Colonies Edit

See Federation colonies.

The exact status of Federation colonies has never been clearly established. While due to the large amount of colonies it seems unlikely that they have full member status, one can imagine them them enjoying a status not unlike to that of Federation protectorates.

Proposed members Edit

Other possible members Edit

Species with Representatives in Starfleet Edit

The following homeworlds have had members in or have sent technicians, advisors, etc. to Starfleet. Barring a special admittance from a high-ranking Starfleet Captain or Admiral, they were most likely citizens. Note that at least one planet is known to have produced a considerable number of Starfleet personel before entering the Federation: Bajor.

Ithenite Homeworld: Homeworld of the Ithenites.
Qo'noS: Homeworld of the Klingons and the Klingon Empire (See also: Klingon planets)
Xindi

It remains unknown if the Xindi have acquired a new homeworld at this time

Coalition of Planets Edit

Four members of the Coalition of Planets became the founding members of the Federation. Coridan joined the federation a century later, in 2267. Since the remaining Coalition members seem to have had close ties with these species, and the coalition of planet has generaly been presented as a precursor to the Federation, the other members might have joined also at some point.

Denobula: Homeworld of the Denobulans. (ENT: "Demons")
Rigelian Homeworld: Homeworld of the Rigelians. (ENT: "Demons")
Six unnamed members.

Sphere of influence Edit

In a 2364 Federation star chart, the following planets were shown to be within the UFP's sphere of influence. (TNG: "Conspiracy")

Whether or not these are Federation members, Federation colonies or planets, surrounded by the Federation space, or simply well-explored areas is unknown. There is no accurate scale given on the chart to determine how many sectors or quadrants are actually shown, nor are any governmental borders specified. Foreign powers are shown interspersed with worlds known to be Federated, so no true allegiances or alliances can be perceived from this background artwork.

Aldebaran III

Possibly the location of Aldebaron colony. (TOS: "The Deadly Years")

Alfa 177: Uninhabited and inhospitable. (TOS: "The Enemy Within")
Alpha Majoris I: Homeworld to the Mellitus and a native population. (TOS: "Wolf in the Fold")
Altair VI: Has a native population and government. (TOS: "Amok Time")
Arret: Uninhabited world. (TOS: "Return to Tomorrow")
Ariannus: TOS: "Let That Be Your Last Battlefield")
Babel

Note that in TOS: "Journey to Babel", this was stated to be in neutral space.

Benecia: Home of the Benecia colony. (TOS: "The Conscience of the King")
Berengaria VII: Scouted as a potential site for the United Earth Starfleet's first starbase. (ENT: "Bound") Presented as a major Federation asset in "In the Cards".
Beta Aurigae: Scientifically examined multiple-star system. No mention of habitation. (TOS: "Turnabout Intruder")
Beta Geminorum system

Other than Pollux IV, its star Beta Geminorum was also mentioned, leading one to think that another inhabited world exists in the system.

Beta Lyrae system: An unknown planet in the Beta Lyrae star system. (TAS: "The Slaver Weapon")
Beta Niobe system

Note that Beta Niobe went nova in 2269, leading one to wonder about how a Federation membership is possible in 2364. (TOS: "All Our Yesterdays")

Beta Portolan system

The planets in this system were decimated long ago, but it may be populated by a colony. (TOS: "Operation -- Annihilate!")

Camus II

Note that it was uninhabited in TOS: "Turnabout Intruder"

Canopus system

Alpha Carinae is mentioned and there are various inhabited planets in its star system, including:

Alpha Carinae II : Has a native population. (TOS: "The Ultimate Computer")
Canopus III : Possibly has a native population, known for a dinosaur species. (TNG: "Eye of the Beholder")

Note that this is seen later on the chart, so it is separate from the other "Alpha Carinae" member.

Alpha Carinae V : Homeworld of the Drella and a native population. (TOS: "Wolf in the Fold")
Canopus Planet : Probably has a native population, home of poet Tarbolde. (TOS: "Where No Man Has Gone Before")

Capella IV: Homeworld of the Capellans and the Ten Tribes. (TOS: "Friday's Child")

Since the planet was pre-industrial, the chart may have been referencing another planet in the Capella system.

Daran V

An inhabited planet. (TOS: "For the World is Hollow and I Have Touched the Sky")

Deneb system

An inhabited planet in the Deneb system of which there are four.

Deneb II : Contains a native population. (TOS: "Wolf in the Fold")
Deneb IV : Homeworld of the Bandi and another telepathic species. (TOS: "Where No Man Has Gone Before")
Deneb V : Homeworld of the Denebians. (TOS: "I, Mudd")
Alpha Cygnus IX : Possibly inhabited. (TNG: "Sarek")

Delta Vega

An uninhabited planet and Federation outpost. (TOS: "Where No Man Has Gone Before")

Eminiar system

An inhabited planet in the Eminiar system, of which there are two. (TOS: "A Taste of Armageddon")

Vendikar : Independent Colony of the Eminiar VII.
Eminiar VII : Homeworld of the Eminians and the Eminian Union.

Fabrina: Homeworld of the Fabrini. (TOS: "For the World is Hollow and I Have Touched the Sky")

Note that the original Fabrina was destroyed, so this may be a reference to their colonized home.

First Federation Homeworld: Homeworld of the First Federation. (TOS: "The Corbomite Maneuver")
Gamma Canaris N: Possibly a colony world. (TNG: "Conundrum")
Gamma Trianguli VI: Home of the Vaalians. (TOS: "The Apple")

They don't seem technologically advanced enough to join the Federation, so they might be a protectorate or perhaps there is a more advanced culture elsewhere in the Gamma Trianguli system.

Holberg 917G: An uninhabited planet in the Omega system. (TOS: "Requiem for Methuselah")

Note unless an independent colony was established, it is unknown how this could be a Federation member.

Ingraham B: Possibly a colony. (TOS: "Operation -- Annihilate!")
Janus VI: Homeworld of the Horta and the Janus VI colony. (TOS: "The Devil in the Dark")

Early plans for Star Trek IV: The Voyage Home were to include Horta in the Federation Council scenes.

Kling: A planet believed to be in the Klingon Empire. (TNG: "Heart of Glory")

It is very doubtful that a Klingon planet would join the Federation, as this information would be contradicted in later episodes. In "Samaritan Snare", Wesley Crusher stated that the "Klingons joined the Federation," although this does not necessarily mean membership.

Kzin: Homeworld of the Kzinti. (TAS: "The Slaver Weapon")
Lactra VII: Homeworld of the Lactrans. (TAS: "The Eye of the Beholder")
Makus III: Probably contains a native population and government. (TOS: "The Galileo Seven")
Marcos XII: Possibly a Federation colony. (TOS: "And the Children Shall Lead")
Memory Alpha: An uninhabited planetoid containing the largest Federation library. (TOS: "The Lights of Zetar")
Mudd: Inhabited by androids. (TOS: "I, Mudd")
Omega Cygni system: An inhabited planet in this system.
Omega IV: Homeworld of the Omega IV natives, and specifically the Kohms and Yangs. (TOS: "The Omega Glory")
Organia: Supposed Homeworld of the Organians and the Organian Council of Elders. (TOS: "Errand of Mercy")

While it is unlikely that the Organians are members of the Federation themselves, a colony might have started on the planet following the Treaty of Organia.

Orion: Homeworld of the Orions, and former homeworld of the Orion Syndicate. (TOS: "The Cage")

Note that chart may be referencing the friendlier Orion I.

Phylos: Homeworld of the Phylosians. (TAS: "The Infinite Vulcan")
Psi 2000: An uninhabited planet that disintegrated in 2266. (TOS: "The Naked Time")

Note that it is unclear why this would be on a Federation chart 98 years later, but perhaps this is referring to the Psi 2000's star system, and an inhabited world existed nearby.

Pollux IV: An uninhabited planet. (TOS: "Who Mourns for Adonais?")

It is unknown if a colony was built on this planet.

Pyris VII: An uninhabited planet. (TOS: "Catspaw")

It is unknown why this planet would rise to prominence on the chart.

Regulan system

An inhabited planet in the Regulus star system, of which there are two.

Regulus III : Has a population. (DS9: "Fascination")
Regulus V : Class M, possibly has a population. (TOS: "Amok Time")

Sarpeid system: An inhabited planet in the Sarpeid star system.
Sirius IX: Homeworld to a native population and a planetary government. (TAS: "The Slaver Weapon")
Talos IV: Homeworld of the Talosians. (TOS: "The Cage")

Note that the Talos IV was considered off limits in 2267. The chart simply mentioned "Talos," so there may be another population in the system.

Tau Ceti system

An inhabited planet in the Tau Ceti star system of which there are three:

Tau Ceti Prime : Possibly a colony or resort planet. (VOY: "Coda")
Tau Ceti III : Possibly a colony, but may be inhabited. (TNG: "Conspiracy")
Tau Ceti IV : Home of the ship port Amber. (Star Trek II: The Wrath of Khan)

Theta III
Tholian Homeworld: Homeworld of the Tholians and the Tholian Assembly. (TOS: "The Tholian Web")

The chart mentions the Tholian Assembly to be precise. Later references in TNG made the Tholians' inclusion in the Federation unlikely.

Others Edit

A number of planets might be suspected to be Federation members for other reasons.

Argelius II: Homeworld of the Argelians. (TOS: "Wolf in the Fold")

Mentioned to be "a port for Starfleet".

Camor V: Homeworld of the Camorites. (TNG: "Bloodlines")

Camor V was apparently involved in the Cardassian Wars, suggesting it was associated either with the Cardassian Union or the Federation.

Ktaris: Homeworld of the Ktarians. (VOY: "The Voyager Conspiracy")

The exact status of the Ktarians remains unclear. In 2368 the Ktarians seemingly tried to gain control of Starfleet and the Federation, but by 2376, in VOY: "The Voyager Conspiracy", Seven of Nine stated that "the Ktarians were officially with the Federation, but they sympathized with the Maquis". This suggests they may be a member of the Federation, or allies.

Angel I: Homeworld of the Angel I natives

In 2364 it was the hope of Starfleet that the planet might one day become a member of the Federation, though no concrete steps seem to have been taken.

Appendices Edit

Apocrypha Edit

Aurelia: Homeworld of the Aurelians. - Aleek-Om was identified as a "Federation historian" in the Star Trek Concordance, possibly based on the script.
Bilana III: Has a population - member according to the Star Trek Encyclopedia
