Sirius (also Alpha Canis Majoris or the "Dog Star") is a star system consisting of binary companion stars, Sirius A and Sirius B, located about 8.6 light years from Sol. This system was located in the Alpha Quadrant.

In 2267, Sirius was one of the stars Lieutenant Sulu used to calculate the Enterprise's position after it had been displaced 500 parsecs by the Metrons. (TOS: "Arena")

Sirius was most notable for the fact that, after the last Kzin War, in the mid-to-late 21st century, the Treaty of Sirius was signed in this system, ending the series of wars between Earth and the Kzin government. (TAS: "The Slaver Weapon")

The Sirius Cybernetics Corporation originated in this system. (TNG: "The Schizoid Man"; Star Trek: Deep Space Nine set decorations)

In 2364, Sirius was noted on a large star chart at Starfleet Headquarters. Also, on several other occasions that year, viewscreen readouts aboard the USS Enterprise-D showed the location of the A and B Sirius stars, in the form of charts from the Enterprise library computer. (TNG: "The Naked Now", "The Last Outpost", "Conspiracy")

Background Edit

The Enterprise computer's star chart was a drawing by Rick Sternbach that had originally been published, years earlier, on page 77 of the non-canon reference book Spaceflight Chronology. This chart showed Earth commercial and exploration routes after the use of warp drive began. Sirius A was a destination on an exploration route.

The Starfleet HQ chart was the image behind the chair in the room where Dexter Remmick was killed in "Conspiracy".

The Sirius group was mentioned in Gene Roddenberry's original Star Trek pitch in one of the suggested story lines. In the storyline "Kentucky, Kentucky," the Sirius group was home to an Earth colony for fifty years. This colony was attacked by viking-like savages and reduced to a "frontier" log-fort life. They were regrouped and led by Captain Robert April when the SS Yorktown visited the colony.

Sirius was a real system in the Canis Major constellation. Modern scientists have determined Sirius's components are spectral classes A1V and dA2.
