A · B · Proxima

LITAlpha Centauri A and B orbit each other every about 79.9 years (semi-major axis about 23.4 AU, e ≈ 0.52; masses about 1.08 and 0.91 M☉). Proxima Centauri, the nearest star at about 4.24 ly, orbits the pair at about 8,700 AU with a period near 550,000 years (Kervella et al. 2017). That makes a true triple, the ternary of this run's keywords.
