: I wish someone had asked what the deal is with Sigma Octanus - is it actually
: a misspelled Sigma Octantus, which lies 270 lightyears from Earth, or is
: it a different, coincidentally named system? That's always bugged me. Of
: course, it could be a reverse Harvest - lying hundreds of real lightyears
: away, but practically on the front door via slipspace.

Not in Cannon Fodder, but through the Catalog posts--someone asked about the discrepancies between Epsilon Indi in reality and in Halo:

http://www.halopedia.org/Catalog/Archive#Post_.231_2

Query: Does the de facto location of the star system known as Epsilon Indi coincide with 21st-century human observations of said system? I ask this because there is a discrepancy between the apparent distance to said system (Harvest being humanity's most distant colony) and early observational evidence of the system being only 11 light-years from Earth and thus only half a light-year further than one of the closest colonies, Reach.
Query Answer: [slip stream space] transit records record liminal [sphere] colony [ref: Harvest] as furthest official Human colony. [slip stream space] topology is not consistent with [Euclidean] distance, but significant discrepancy is noted.
