The '''Sigma Octanus system''' is a planetary system with at least four planets orbiting a binary star, and is identified as a region in [[FLEETCOM Sector Three]].<ref>'''Halo: The Fall of Reach''', ''page 211''</ref> The system is home to the [[human]] colony world of [[Sigma Octanus IV]], which had a population of over 17 million people prior to the [[Battle of Sigma Octanus IV]].<ref>'''Halo: The Fall of Reach''', ''page 144''</ref>

==Trivia==
==Trivia==
While there is in fact no actual star with the designation "Sigma Octanus", there is one named "Sigma Octantis", a slight spelling change, located 270 light years from the [[Sol system]]. However, it is unlikely to be the same system for a number of reasons. The real-world Sigma Octantis is classified as a F0 III-type giant instead of a binary star. In addition, it would make Sigma Octanus the second furthest known [[United Nations Space Command|UNSC]] colony, significantly further than the [[Outer Colonies|Outer Colony]] system [[23 Librae]] which was considered to be "behind enemy lines" by 2535. Furthermore, the {{UNSCShip|Iroquois}} traveled from the system to [[Reach]] in less than a month. Traveling over 250 light years in such timeframe would be difficult with human slipspace velocities.
*While there is no actual star with the designation "Sigma Octanus", there is one named "Sigma Octantis" located 270 light years from the [[Sol system]]. However, it is unlikely to be the same system for a number of reasons: The real-world Sigma Octantis is classified as an F0 III-type giant instead of a binary star. In addition, such distance would make Sigma Octanus the astronomically farthest known UEG colony, significantly farther than the [[Outer Colonies|Outer Colony]] system [[23 Librae]] which was considered to be "behind enemy lines" by 2535. Furthermore, {{UNSCShip|Iroquois}} traveled from the system to [[Reach]] in less than a month. Traveling over 250 light years in such timeframe would be difficult with war-period human slipspace velocities.
*Although the system contains a binary star,{{Ref/Reuse|binary}} one of the stars (likely the primary) is apparently known as Sigma Octanus as it is stated that "light from Sigma Octanus" reflected off the debris of the battle in the system.<ref>'''Halo: The Fall of Reach''', ''page 215'' (2001)</ref>
