The Babylon Project

Yellow Sector is an area of Babylon 5 that contained the primary fusion core, fuel tanks, and variable gravity research labs and zero-g maintenance. Yellow Sector encompasses the "spine" of the station, as well as the non-rotating section at the rear.


  • It's possible that some parts of Yellow Sector were in fact within B5's rotational sections as in ("TKO"), the area in which the Mutai is held had yellow sector markings running the length of the halls and that area quite obviously had gravity.
