Rigel VII was the inhabited seventh planet of the Rigel system in the Alpha Quadrant. The planet had one moon. This was the homeworld of the Kalar, a pre-warp humanoid species. The Rigel VII Lagrange colony was associated with it. (TOS: "The Cage", "The Menagerie, Part I", "The Menagerie, Part II"; TNG-R: "Inheritance")


In the 2250s, Rigel VII was several weeks away from the Vega colony at the maximum cruising speed of a Constitution-class heavy cruiser. (TOS: "The Cage", "The Menagerie, Part I")

In 2254, a landing party from the starship USS Enterprise, led by Captain Christopher Pike, visited Rigel VII. While inside an apparently abandoned Kalar fortress, Pike and crew were attacked by the native Kalar warriors. Three crew members, including Pike's personal yeoman, were killed. Seven more were injured (including Spock, Navigator Tyler and a ship's geologist); some of these were so severely wounded that they required treatment at the Vega colony. Pike later regretted his decision to enter the fortress, stating that "the swords and the armor" should have alerted him to the possibility of a trap. (TOS: "The Cage", "The Menagerie, Part I", "The Menagerie, Part II")

There was a song called "Moon over Rigel VII". Captain Kirk proposed singing it around a campfire while taking shore leave at Yosemite National Park on Earth with Captain Spock and Doctor McCoy in 2287. (Star Trek V: The Final Frontier)

In the 24th century, Lieutenant Robert Blackman, a crewmember aboard the USS Enterprise-D, was born on this non-Federation planet. In 2369, his planet of origin was listed on the chart "USS Enterprise Personnel Database", which was seen on Jean-Luc Picard's PADD. (TNG: "The Chase" okudagram)

During the 2360s, Kobliad fugitive Rao Vantika used a subspace shunt to access and purge everything in the active memory of computer systems on Rigel VII. He later attempted the same on Deep Space 9 in 2369. (DS9: "The Passenger")

In the 2370s, a view of the surface of Rigel VII was depicted on several viewscreens on Deep Space 9's Promenade and replimat, advertising a visit to the "spectacular castles of Rigel VII". (DS9: "Whispers", "The Muse", "What You Leave Behind")


Background information

This planet's quadrant of origin is inferred based on the position of its star system as seen in the star chart appearing in Star Trek VI: The Undiscovered Country.

In the story outline for "The Cage" (as reprinted in The Making of Star Trek, pp. 47-65), this planet's name was given as "Endrex II". (The Making of Star Trek, p. 51) As evidenced by the script for "The Cage", the planet's name was then changed to "Rigel 113". Before it finally became "Rigel VII", Harvey P. Lynn – a physicist from the RAND Corporation who served as an unofficial adviser on both "The Cage" and, later, the first season of Star Trek: The Original Series – suggested to Gene Roddenberry that he consider changing "Rigel 113" to "Vega 113", due to Rigel being "mighty far away." (The Making of Star Trek, p. 95)

In stage directions from the first draft script of "The Cage", Rigel 113 was mentioned as having an "adobe-type terrain." The same script also remarked, "The sky is reddish, a quarter of it dominated by a huge moon." In the second revised final draft of the script for "The Cage", the planet's surface was described as featuring "rocks and strange vegetation."

In "The Cage" and "The Menagerie, Part II", the surface of Rigel VII (including the exterior of the Rigel fortress) was depicted with a matte painting that was created by Albert Whitlock. The same matte painting was re-used, unaltered, for Holberg 917G in the original version of TOS: "Requiem for Methuselah" (though it was replaced by a new CG matte painting for that episode's remastered version).

Mark A. Altman appreciated the Rigel VII matte painting, commenting, "It belongs in a museum! It's stunning!" ("Strange New Worlds: Visualizing the Fantastic", Star Trek: The Original Series - The Roddenberry Vault special features)

The live-action part of Rigel VII was filmed on location at the "Arab Village" section of Desilu's 40 Acres backlot in Culver City, California. (These Are the Voyages: TOS Season One, 1st ed. p. 61)

According to, Rigel VII was in a double planet system. [1]

According to Star Trek: Star Charts (p. 54; "United Federation of Planets III"), Rigel VII (Beta Orionis A VII) was a quarantined planet. The planet was an Class M world. The planet was non-aligned, with its status pending the development of warp drive. The dominant species was the Kalar. There was a conjectural count of 725,000 Kalar in 2370. First contact with this world was made by the Enterprise in 2254. This planet was in the Beta Quadrant, in the "true" Rigel (Beta Orionis) system.


In the short story version of "The Cage" (titled "The Menagerie" and published in Star Trek 4), this planet was Rigel VIII.

According to the comics series Star Trek: Early Voyages, the building was named the Zemtar fortress, and the Kalar warriors attacked because of their reluctance to see their homeworld join the peaceful Federation.

In Decipher's Star Trek Roleplaying Game, the green Orion race was from Rigel VII.
