Gamma Trianguli sector
From Memory Alpha, the free Star Trek reference.
The Gamma Trianguli sector is a sector of space containing, among other things, Archer's Planet. (ENT: "In a Mirror, Darkly, Part II")
[edit] Background
The Star Trek: Enterprise fourth season episode "In a Mirror, Darkly, Part II" revealed this sector reference, as well as the planet's name, in text appearing in Jonathan Archer's personnel file. The original production artwork can be viewed at MikeSussman.net.
Presumably Gamma Trianguli VI, referenced in TOS: "The Apple" is located within this sector as well.
In the non-canon comic "Paradise Lost!", Gamma Trianguli's sector was referred to as "sector 18".
