Background information Edit
Vega is a real star about 25 light years from Earth. The Vega colony, presumably at Vega, was established prior to 2151. According to "Two Days and Two Nights", no Earth ship had been operating as far as 90 light years of the Sol system, suggesting that (the fictional version of) Vega was closer then that.
According to the Star Trek: Star Charts pp. 36, 44, the Vega system was located in or near Federation space, in the Alpha Quadrant. This system, also known as Alpha Lyrae, was a single star system. Primary was a Class A star with a magnitude of +3, which was ten times the brightness of Sol. In the mid-22nd century, this system was a destination on the Earth trade routes. In the late 24th century, this system was a destination on the major space lanes.
