The following are unnamed Alpha and Beta Quadrant star systems.
Akaali system
Located 78 light years from Earth. this inhabited system was in the general vicinity of a cluster of three neutron stars and a J'ral class supernova remnant. The Akaali homeworld was located in this system. In 2151, Enterprise NX-01 defeated a Malurian starship in this system. (ENT: "Civilization")
Amargosa system
This system accompanied the star Amargosa and included the Amargosa observatory, a space-based Federation facility. In 2371 the facility was attacked by Romulans, sparking concern of a new Romulan threat in the sector. At the time the Enterprise detected no ships in the system, though a cloaked Klingon ship was present. Shortly thereafter, a trilithium weapon launched into Amargosa by the rogue scientist Tolian Soran triggered the star to collapse, producing a level twelve shock wave expected to destroy everything in the system. (Star Trek Generations)
Arret system
The system was located hundreds of light years past the limits of Federation exploration in 2268. That same year, the USS Enterprise was directed to the planet Arret in this system by the thought energy of Sargon. (TOS: "Return to Tomorrow")
Arret (negative) system
This reverse negative antimatter universe star system was in the same galactic position as the Sol system in the forward positive matter universe. The inhabited planet Arret was located in this system. In the mid-23rd century, Karl Four pointed out the location of his home system on a galactic map to Robert April, James T. Kirk, and Spock. (TAS: "The Counter-Clock Incident")
Azati Prime system
Core of star system
This unnamed star system containing the planet Azati Prime was a Delphic Expanse system. Its primary was a red giant located at coordinates 1127.4 by 4052 by 3901.1. The system also contained at least two more planets and at least two moons, as well as at least one planetoid.
As of 2154 considerable activity existed around two of the inner planets, numerous ships, all Xindi. One of these inner planets was Azati Prime. Further out the system also contained a planetoid, with a moon that contained a monitoring station. The station was one of several lunar outposts in the system, and was destroyed in early 2154.
A large array of thousands of artificial satellites that created a detection grid and security net was deployed in the system, protecting Azati Prime. It was extremely sensitive and had no weaknesses. If one of the satellites was destroyed or disabled, the other satellites filled up the gap. (ENT: "Azati Prime")
Ba'ku system
This Alpha Quadrant system was located in the Briar Patch, a region of space in Sector 441. The system had one planet with life - Ba'ku planet - which was colonized by the Ba'ku. According to Ru'afo, the injector assembly, if fired at the planet Ba'ku, would leave all life in the system dead or dying in six hours. This system was located in Federation space. (Star Trek: Insurrection)
Ba'ku home system
This system was the home system of a group of settlers who founded a colony on the Ba'ku planet in 2066. This system's civilization had technology which could destroy all life and the settlers feared their species was on the verge of self-annihilation. (Star Trek: Insurrection)
Binary system
Enterprise in a binary star system
This binary star system was explored by Enterprise NX-01 in September 2152. Captain Jonathan Archer and Commander Tucker prepared Shuttlepod 1 to visit the surface of an uninhabited planet but were forced to leave when a neutronic wavefront approached. (ENT: "The Catwalk")
Ekos and Zion system
This unnamed star system was home to two M-class planets inhabited by humanoids. Ekos, home of the Ekosians, occupies an orbit inward from its' sister planet, Zeon, home to the Zeons. (TOS: "Patterns of Force")
Eminiar system
The NGC 321 star cluster containing the star system
This star system was located within the star cluster NGC 321. The system's primary was named Eminiar. A planet in this system, Eminiar VII, was inhabited by a native species. This species had colonized the third planet in this system, Vendikar, sometime prior to the late 18th century. (TOS: "A Taste of Armageddon")
Exo III system
Exo III was located in a system of which the sun had been fading for half a million years as of the 23rd century.
Gosis' species star system
Gosis' species system was a system with only one class M planet.
When Enterprise NX-01 visited his planet in 2152, Temec reasoned that the Humans must have come from an alien system, since "none of the other planets are capable of supporting life." (ENT: "The Communicator")
Iotian system
Described by Captain James T. Kirk as being on "...the outer reaches of the galaxy", this unnamed star system had at least two planets. The second planet, Sigma Iotia II, was the homeworld of the Iotians. (TOS: "A Piece of the Action")

Uncharted binary system
This uncharted binary star system was located inside a Tyken's Rift. In 2367, a mysterious alien became trapped in the rift and with the help of the Enterprise-D magened to escaped. (TNG: "Night Terrors")
J'naii system
This unnamed system system harbored the planet J'naii, homeworld of the J'naii. It also harbored a null space pocket, a fact which was only discovered in 2368. (TNG: "The Outcast")
New Berlin Colony system
This unnamed system was administered by the Federation New Berlin Colony. In 2369, the colony sent out a distress call fearing a Borg incursion, while all that had happened was that a Ferengi trader had entered their system. (TNG: "Descent")
Romulan-held system
This system, uncharted according to Starfleet, had several planets including one that was Minshara class. The system turned out to be claimed and defended by the Romulan Star Empire, which did not tolerate others entering it. (ENT: "Minefield")
Suliban hiding system
The stars of the system
The stealth cruiser cloaked on a moon in the system
This binary star system was located 2.5 light-years from Paraagan II. It contained at least 2 planets, and at least 2 moons.
In 2152, a Suliban stealth cruiser hid on the inner moon of the second planet orbiting the smaller star in the system. Enterprise (NX-01) disabled the Suliban cruiser in this system and stole its data disks to prove it wasn't responsible for the destruction of the Paraagan mining colony. (ENT: "Shockwave")
System with Kuiper belt
System with a Kuiper belt
In 2375, Odo and a defective Weyoun clone managed to evade capture by Jem'Hadar by hiding in this system containing a Kuiper belt. (DS9: "Treachery, Faith and the Great River")
Terra Nova system
The system of Terra Nova
A display graphic demonstrated Terra Nova to be part of a solar system containing several other planets. (ENT: "Terra Nova")
Tholian system
This system was home to the xenophobic Tholians. When Enterprise encountered a Tholian vessel in 2152, T'Pol remarked that it was unusual for Tholians to travel that far from their system. (ENT: "Future Tense")
Uncharted solar system
This uncharted solar system, located at 2466 PM, contained a planet where the Metrons forced Kirk to fight a Gorn captain. (TOS: "Arena")
War games simulation system
In a holographicly simulated tactical scenario played out on USS Voyager in 2371, a red giant system with eight planets, none of them M class, played a minor role. (VOY: "Learning Curve")
