The 16 Cygni System
Also known as 16 Cyg, Cygnia, or Mycillia by humans, this system is a triple star system consisting of two yellow dwarf stars like our sun (16 Cyg A and 16 Cyg B) and one red dwarf star (16 Cyg C). In this Universe there is one known planet, 16 Cyg Bb, but in the "Through Time" series, there are three other terrestrial planets, one of them containing life (16 Cyg Bc). This planet is a major player in the local interstellar area during its civilization's lifespan, and is a major component in the "Through Time" series.
