Proxima is gravitationally associated with the bright pair Alpha Centauri A and B, making the Alpha Centauri system a triple. Proxima orbits the pair at a great distance and currently sits slightly closer to us than they do.
Like many red dwarfs, Proxima is a flare star, prone to sudden bursts of activity. It is known to host at least one exoplanet, Proxima b, which makes the nearest star also one of the nearest known planetary systems.
How this connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
