Proxima Centauri is a star system which is near to planet Earth. It is also the star cluster in which Planet Furon, the Furon Homeworld resides. Officially, it is in the triple star system consisting of Alpha Centauri A, a sun like star, Alpha Centauri B, a larger but still sun like star and Alpha Centauri C or Proxima Centauri, a very small red dwarf. It is approximately 4.43 light years from Earth. Furon orbits around Centauri C, the smaller of the three.
As a red dwarf, it releases massive bursts energy that heavily irradiate the planet, so the Furon race needs its shields to even survive.
