-The name of the system containing the [[RDM Battlestar Galactica|Twelve Colonies]] of man ([[Video Game|Battlestar Galactica video game]]).

-It is unclear whether it is accepted as [[canon]] within the re-imaged Battlestar Galactica television series, or whether it is a single star with multiple life-bearing planets, or a [[#Binary Stars|binary]], a trinary star system, or an [[#Open Star Clusters|open cluster]] of stars.
-== Potential of A Single Star ==
-While it has been ascertained through searches undertaken from both the surface of the Earth and the [[Wikipedia:Hubble_Space_Telescope|Hubble Space Telescope]] that there are a large number of planets orbiting local stars in our galaxy, most of the planets discovered to date are clssified as gas giants, similar in size and potentiallyy in composition as the planet [[Wikipedia:Jupiter_%28planet%29|Jupiter]] in our own solar system.
-Further, it is believed that there is a very narrow band of space around a star that will encourage the formation of life-bearing planets (the so-called "zone of life"). This is a region of space where the heat from the sun is neither too hot nor too cold to prevent the natural development of life through chemical and then organic means.
-It is highly improbable that a single star would have no fewer than twelve planets and moons orbiting a star within the "zone of life" for that star. This would indicate that it is doubt the 12 colonies exist within the planetary system of a single star - unless the Colonials have the ability to carry out considerable [[Wikipedia: Terraforming|terraforming]]; something that is not indicated given their current technological capabilities.
-Given that Colonial vessels are capable of high sublight velocities (vessles being able to travel between worlds in hours), it is somewhat unlikely that they would need to develop or continue to use a [[faster than light|FTL]] propulsion system.
-For these reasons, and although there has been no confirmation of this within the re-imagined Battlestar Galactica, it is reasonable to assume that if the Cyrannus system is the home of the 12 colonies, that it is in fact a binary or possibly loose trinary star system.

-Hey, My name Is Lane
-Me And My Dad Came Up With A Way This Could Work.
-You See IT IS POSSIBLE To Have 3 ORBITS Within A "Life-Zone" According To Everything We Are Coming Up With There Could Be Up To 4 Planets In 1 Orbit So Therefore You Could Have 12 Planets In The Orbits Of What Would Be Say VENUS,EARTH, And MARS
-A binary star system, with stars in the G-K spectral range offer the possibility of each star developing its own "zone of life" (and potentially planets therein), will the variable distance between the two stars as they orbit one another would potentially encourage the use of some form of "jump" drive to move rapidly between worlds orbiting the different suns.
-The use of a binary star system would be more in keeping with the "reality" sought for by the creators of the re-imagined Battlestar Galactica, and would present the opportunity for moons to be potentially used as colony "worlds" as well as planets.
-==Binary Stars==
-[[Wikipedia:Binary_stars|Binary stars]] are stars bound by a common gravitational force such that they orbit around a common point in space. Their spectral types can vary quite widely, and it is questionable as to whether all binaries will be capable of producing stable planets due to the degree of gravitational flux between the stars.
-Binary star systems can alos form the centre of heirarchical triple (trinary) systems (a binary system with a third star orbiting both) at a much greater distance.
-Cyrannus might be considered a binary star system because such systems, while containing multiple stars, are oftern referred to by a single name.
-=== Example of a Binary Star System ===
-The [[Wikipedia:Alpha Centauri|Alpha Centauri]] system is a prime example of both a binary star system and an hierarchial triple star system. a multiple-star system having a single name.
-Alpha Centauri comprises a true binary system, Alpha Centauri A and Alpha Centauri B, both of which are of the correct spectral types to sustain life-bearing planets. They in turn are orbited by a third star at a much greater distance (Proxima Centauri), thus making the system an hierarchial triple. Proxima Centauri is classified as a red dwarf, and thus is believed incapable of bearing life-sustaining planets.
-==Open Star Clusters==
-Open star clusters, as their name suggests, are groupings of multiple stars in relatively close proximity to one another which are not bound together by gravity (although a star cluster can contain [[#Binary Stars|binaries]] among its number. Due to the number of stars within a cluster, the possibly of several being able to support life-bearing planets might be considered high.
-There are several advantages in considering Cyrannus to represent a star cluster (or for the [[Twelve Colonies#RDM Battlestar Galactica|Twelve Colonies]] to be within an open star cluster:
-* A star cluster may present a much large number of stars capable of supporting life-bearing planets
-* The distances between stars would be much greater than a binary system, and would help explain why some vessels operated by the Colonials are so luxuriously equipped or outfitted for long duration flights, as it would most likely require vessels to make multiple jumps between stars, thus measuring journey times in terms of days (or possibly weeks).
-* A star cluster might explain why the Colonials don't appear to have undertaken much in the way of really deep-space exploration. They might have been engaged in simply surveying other stars within the cluster (thus having knowledge of the [[Promar Sector]], but at the same time being oblivious to the precise location of [[Kobol]] relative to their own worlds).
-* A star cluster would give the [[Cylons]] ample opportunity to hide away from Colonial eyes, while still keeping a check on (and perhaps influence) Colonial activities.
-===Example of an Open Star Cluster===
-The [[Wikipedia:Pleiades_%28star_cluster%29|Pleiades]] cluster is a classic exmaple of an open star cluster, although it is one that contains relatively young stars, many of which are burning too hot to sustain life-bearing planets.
-==[[TOS Battlestar Galactica|Origins]]==
-In the [[TOS Battlestar Galactica|original series]], the [[TOS Battlestar Galactica|Twelve Colonies]] were said to be located in the [[Cyranus (TOS)|Cyranus]] system (note spelling). While it is accepted this is a multiple star system, its exact nature and composition is unknown.
