x2 Centauri is astar located in theconstellationCentaurus. It is also known by its designationsHD 108114 andHR 4724. Theapparent magnitude of thestar is about 5.7, meaning it is only visible to the naked eye underexcellent viewing conditions. Its distance is about 440light-years (140parsecs), based on itsparallax measured by theHipparcosastrometry satellite.[1]
x2 Centauri'sspectral type is B9IV/V, meaning it is a lateB-type main sequence star orsubgiant. These types of stars are a few times more massive than theSun, and haveeffective temperatures of about 10,000 to 30,000K. x2 Centauri has a temperature of about 11,500 K.[7] The starx1 Centauri, which lies about 0.4′ away from x2 Centauri, may or may not form a physicalbinary star system with x2 Centauri, as the two have similarproper motions and distances.[9]
