In the author's original timeline, Beta Station was founded in 2039 by ECS3 Argo as the fourth star station supporting the sublight "great circle" circle. Beta Station is located in the Alpha Centauri star system, a trinary system 4.37 light years from Sol. Alpha Centauri A is a G2 class main sequence star slightly larger than Sol; Alpha Centauri B is a K1 class main sequence star sliglhtly smaller than Sol. The pair orbit each other with a period of 80 years, but the orbit is elliptical. Closest approach for the pair is approximately equivalent to Sol and Saturn, with greatest separation approximately that of Sol and Pluto. The third member, Proxima Centauri, is an M6 red dwarf orbiting the binary system at a distance of 0.24 light years. Alpha Centauri is located generally in the o
