Beta Centauri is a trinary star system in the Milky Way Galaxy and is about 390 light-years away from Earth.
- The fact that Tony Stark: Iron Man #17 confirms that the Centaurians who exist in the Prime Universe live on a planet (presumably Centauri-IV) located in the Alpha Centauri star system means that the Beta Centauri star system has never been part of any story set in the Marvel Universe. Every bit of data on this page actually applies to the Alpha Centauri star system instead.
