Orion system vicinity

Gamma 400 vicinity.

Gamma 400, also known as Aladso, was a star system located in the Fries-Posnikoff sector (TNG novel: Ship of the Line), in the Beta Quadrant (ST reference: Star Charts). It lay in Federation space and was close to the Klingon Neutral Zone and the Orion Neutrality Area. (ST reference: Star Charts; FASA RPG - The Orions module: Book of Common Knowledge)

This system was also near the Tau Eridani Cloud. (TOS novel: Ishmael)

Gamma 400 was a binary star system, with an M class red primary and an F class white secondary. It had a brightness of magnitude +5. (ST reference: Star Charts)

This system was the location of Starbase 12. (TOS episode: "Space Seed")

Gamma 400 was a Federation system. (ST reference: Star Charts)

The system contained over 5 planets and its outer worlds had moons. The only class M planet was the third, Rontelm. Rontelm, the fourth and fifth planets and the moons of the outer planets all had mines that supplied Starbase 12's factories. (FASA RPG - The Orions module: Book of Common Knowledge)

Starbase 12 was canonically placed in the Gamma 400 system in Space Seed, but The Orions: Book of Common Knowledge placed Starbase 12 in the Aladso system. Therefore, it is assumed that these are the same system: "Aladso" is likely an Orion name for Gamma 400.
