A star in the Argolis Cluster

In 2368, the USS Enterprise-D hid in the chromosphere of this star. (TNG: "I Borg")

Arkonian planet sun

An unnamed planet claimed by the Arkonians had a nearby sun, which caused issues for an Arkonian and Human that were stranded on a moon of the planet in 2151. (ENT: "Dawn")

This star in the Badlands was orbited by a gas giant that itself was orbited by at least one moon. (DS9: "Heart of Stone")

Beta Magellan system primary

Bynaus, remastered

Beta Magellan

Beta Magellan was a star in the Beta Magellan system. A companion star in this system went supernova in 2364. The supernova occurred earlier than the nearby Bynars anticipated, and the resulting electromagnetic effects disabled their planetary computer on Bynaus. (TNG: "11001001")

Binary stars

These two stars of a binary star system caused only four nights in a month on an orbiting planet. (ENT: "The Catwalk")

Boreth primary

This star was the primary of the planet Boreth. In the 9th century, according to The Story of the Promise, Kahless pointed to this star and informed his followers that they could find him there after he returned from Sto-vo-kor. In the centuries that followed, the Klingons established a monastery on Boreth, awaiting for his return. (TNG: "Rightful Heir")

Borg renegade star

Exo III sun

As of the 23rd century, the sun of the star system including Exo III had been fading for half a million years. As it did, the inhabitants moved underground. (TOS: "What Are Little Girls Made Of?")

The sun might conceivably be named on a fact sheet on the planet that appeared in the episode but was unreadable on screen. The word "orbit" can be deciphered on the graphic.

Gamma 7A sun

This fourth magnitude sun was the primary of the Gamma 7A system, in Sector 39J. In 2268, this star was destroyed by a space amoeba. (TOS: "The Immunity Syndrome")

Gamma Canaris N sun

This sun was orbited by an asteroid belt that contained the planetoid Gamma Canaris N.

Kavis Alpha sector binary

Kavis Alpha sector

Kavis Alpha sector binary

This unnamed binary star system in the Kavis Alpha sector consisted of a red giant and a neutron star. Every 196 years, there was a stellar explosion in this system, when the smaller neutron star shedded the accumulated matter it had sucked up from the larger star over the intervening years.

The Mintakans took measurements for their sundials when this sun reached the zenith. (TNG: "Who Watches The Watchers")

This sun was only mentioned in dialogue.

Monac sun


Monac in 2375

Monac was the primary of the Monac planetary system.

In 2375, the IKS Rotarran, under the command of General Martok, successfully triggered a solar plasma eruption from the surface of the Monac sun from a magnetic instability near the equator. The resulting explosion destroyed the Monac shipyards, located near the star. (DS9: "Image in the Sand", "Shadows and Symbols")

Monac was named after DS9's special effects supervisor Gary Monak. (Star Trek: Deep Space Nine Companion, p. 598)
According to Star Trek: Star Charts (p. 46), Monac was classified as a K-type star. This star, and its system, were located in the Alpha Quadrant.

Necro cloud star

Necro Cloud

The Necro cloud and the star near it

The Necro Cloud was located near this star. (Star Trek Beyond)

This may have been the the same star as the sun of Altamid, given its proximity to the planet.

Operation Return battlefield

Psi 2000 sun

The planet Psi 2000, once remarkably like Earth, became a frozen wasteland after its sun "went dark". (TOS: "The Naked Time")

Romulan system primary

Romulan system map

Romulan sun

This was the star around which Remus orbited. One side of Remus never saw the sun, and neither did Shinzon while he was exiled there. (Star Trek Nemesis)

Both dialogue and the graphic shown in Nemesis suggest a single sun, in contradiction to the Star Trek Maps (p. 29) and The Worlds of the Federation (p. 148), which both place the Romulan star system around a binary star system of two White dwarves.

Sector 1156 star

Sector 1156 star

A star in Sector 1156

This star in Sector 1156 was orbited by the D'Arsay archive that at first appeared to be a rogue comet. (TNG: "Masks")

Sigma Draconis star

Sigma Draconis system

The Sigma Draconis primary

The primary of the Sigma Draconis system was classified as spectral type gamma-9.

The position of this yellow dwarf star was depicted on a system map that was displayed on the main viewscreen of the USS Enterprise bridge in 2268. (TOS: "Spock's Brain")

According to Star Trek: Star Charts (pp. 18, 19, 44) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), this Alpha Quadrant star was named Sigma Draconis and was located in Sector 004 (Sigma Draconis sector).

Supernova of 2387

In 2387, a star in close proximity to Romulus went supernova, threatening nearby systems. To stop the threat, Ambassador Spock used red matter to create a black hole that consumed the star's energy. Before he could successfully carry out his mission, however, the supernova reached Romulus, destroying the planet and all of its inhabitants. Among those killed were the wife and unborn child of Nero, who swore vengeance against Spock, Vulcan, and the Federation for letting his world die. While Nero confronted Spock, both of their ships were pulled into the black hole that had consumed the star, sending them back in time and resulting in the creation of the alternate reality. (Star Trek)

In the script of Star Trek, this star was referred to as being in the Beta Quadrant. [2]


Having a supernova threaten the entire galaxy is a physical impossibility under normal circumstances: the law of special relativity limits the shockwave's expansion rate to below the speed of light, meaning it would be a minimum of several years before it affected even nearby stars. The expansion of the blast wave would also result in it weakening and dissipating over time. This means it should be impossible for any such event to cause severe damage to a warp-capable, multi-planetary society such as the Romulan Star Empire, let alone the entire galaxy. This discrepancy was explained several different ways in non-canon works.

In the comic book series Star Trek: Countdown, this star and its system were named "Hobus". The comic explained that the star's galactic threat came from its unusual ability to transform anything it contacted into energy, which it then consumed, increasing its power and causing it to expand farther and faster throughout the galaxy.

The Star Trek novelization instead stated that the star had merely threatened systems in its own vicinity rather than the entire galaxy.

A third explanation appears in the backstory of Star Trek Online, which states that the shockwave from the Hobus explosion propagated through subspace at faster-than-light speeds and reached the Romulan system in just over a day, destroying both Romulus and Remus mere hours into an evacuation expected to take six weeks. A scandal occurred several years later involving rumors that the Vulcan Science Academy knew about the instability of the star but did nothing until Spock attempted to save Romulus with the Jellyfish. The scandal resulted in several resignations and sowed seeds of distrust towards the Vulcans.

It is revealed during the course of Star Trek Online itself that the supernova was not a natural occurrence: the supernova and the unusual behavior of its shockwave were caused by an Iconian-designed doomsday weapon deployed by rogue members of the Tal Shiar. Then-Admiral Taris led the operation but claims to the player character that she was deceived about the nature of the Iconian device by her then-science officer, Hakeev.

In the more recent reference book Stellar Cartography: The Starfleet Reference Library ("Stellar Cartography", p. 35), the explosion of Hobus was called a "subspace supernova". This event resulted in the destruction of the entire Romulan star system, with billions killed. The cause of the explosion was unclear. The star was located in the Beta Quadrant. There was some contention on where precisely the star was located. On p. 35, the star was located in the Romulan Neutral Zone. Yet, in the "Federation Historical Highlights, 2161-2385" and "Position of the Romulan Star Empire", the star was located "southeast" of Romulus and quite some distance from the Neutral Zone. On the "Position of the Romulan Star Empire", which was a map of the Romulan Empire – prepared by the Stellar Archive Artist Lsel Essik, from the Romulan Master Data Catalog, in 2366 – Hobus was identified as a Romulan system.
