Planets in Stargate

From Wikipedia, the free encyclopedia

Diagram of how Stargate addresses correspond to seven points in space from which a destination and journey can be extrapolated. Largely this is how planets are located and named in Stargate.

This article provides a list of fictional planets featured in the science fiction television shows Stargate SG-1 and Stargate Atlantis.

See also: Humans in SG-1, Humans in Atlantis.

In the Stargate fictional universe, the use of Stargate devices, and much later in the series, a small number of space-faring vessels, humans of Earth have come into contact with a large number of other Earth-like, populated planets. Whilst most planets are shown only once, and then revisited periodically in the background of the show, some planets become key locations in the plot. Examples include the planet Abydos, the original planet visited in the Stargate movie; Chulak, Teal'c's homeworld; Dakara, the centre of the newly-formed Free Jaffa Nation; and Langara, homeworld of Jonas Quinn.

Some critics of the show point to the implausibility that 99% of planets encountered are habitable to humans, and are ultimately very similar to Earth. This is in fact an oversight: the Stargates were not scattered randomly, but rather were placed selectively on planets like Earth; thus planets like Earth are the only destinations reachable. In addition, the use of MALPs means that episodes simply do not occur on non-Earthlike planets. Likewise, the reason that most planets are inhabited by humans is that the Stargates were used predominantly by the Goa'uld for carting humans from Earth to other planets as slaves. Further, it has been stated that the Goa'uld terraformed many new planets over thousands of years to be more habitable for their human slaves.^[1]

Some of the planets listed were taken from the cartouche on Abydos, as this was originally thought to be the only planet that could be dialed from the Earth stargate. However, after visiting the cartouche, the SGC were able to make the correct calculations compensating for stellar drift.

The list of planets is separated by the galaxies in which planets are found, as travel tends to be restricted to within one galaxy - the Milky Way in SG-1, and the Pegasus Galaxy in Atlantis. Where available, the Stargate address and SGC designation are included.

Most Stargate-accessible locations are assigned an SGC designation of the form P00-000 (M00-000 is used for moons), where "0" is replaced by a letter or number. "It's based on a binary code the computer uses for extrapolation", according to Samantha Carter ("The Broca Divide"). Dr. Jackson and Lt. Ford ("The Siege (Part 1)") have suggested easier-to-remember nomenclatures without success. However, if the local name of a planet is known then that name is often used in place of the designation.

When dialing a gate, it is important that (within the Milky Way, for the most part) a seventh chevron be encoded - for the point of origin. There are instances where eight chevrons are required - such as dialing distant galaxies, such as Ida (the home of the Asgard) or Pegasus, the location of Atlantis. Additionally, a ninth chevron exists on the Stargate, though its purpose is not yet known.

They met the fate of all advanced civilizations in the Pegasus Galaxy when they were attacked and apparently destroyed some time around 1998 by the Wraith. About 300 Satedans managed to make it to shelters west of the capital, and were later able to escape to planets such as Balkan and Manaria. Working name: Atteria.[49]
Taranis			A world where the Stargate was located in the caldera of a volcano, along with an Ancient facility with a geothermal energy source powering its shield. Half a continent destroyed by said volcano's explosion. [50]

[edit] Ida Galaxy

Planet	SGC Designation	Stargate Address	Notes
Halla			An Asgard planet intended as a prison for the Replicators. Was destroyed when the Asgard turned its sun into a black hole.
Orilla			Asgard's new homeworld, possibly in the galaxy of Ida. Blown up by the Asgard with them on the planet to prevent their kind from suffering from a genetical decease and to prevent other species from getting their technology.
Othala			The original Asgard homeworld located in the galaxy of Ida. It was first visited by the SGC when Jack O'Neill dialed out to the planet, after having the knowledge of the Ancients 'downloaded' into his head. During the battle with the Replicators, however, Othala was overrun and the new Asgard homeworld became Orilla.

[edit] Ori Galaxy

[edit] Other Stargates

Stargates not situated on/orbiting planets.

Location	SGC Designation	Stargate Address	Notes
Klorel's Ship			The gate address is only valid while Klorel's ship is orbiting a particular planet. Once the ship leaves, the address would change.
Midway Space Station			A space station situated in intergalactic space midway between the Milky Way and Pegasus galaxies and containing one Stargate from each of the two galactic Stargate systems. This forms the center span of the McKay-Carter Intergalactic Gate Bridge, a string of Stargates that allows travel between the two galaxies with much reduced energy cost compared to normal eight-chevron dialling.
