'''HD 111597''' is a suspected [[astrometric binary]]<ref name=Eggleton2008/> star system in the southern [[constellation]] of [[Centaurus]]. It has the [[Bayer designation]] ''p Centauri'', while ''HD 111597'' is the star's identifier from the ''[[Henry Draper catalogue]]''. The system is visible to the naked eye as a faint point of light with an [[apparent visual magnitude]] of 4.90.<ref name=Anderson2012/> It is located at a distance of approximately 410 [[light year]]s from the [[Sun]] based on [[stellar parallax|parallax]],<ref name=GaiaDR3/> and has an [[absolute magnitude]] of −0.53.<ref name=Anderson2012/> The system is a probable member of the [[Sco OB2]] association of co-moving stars.<ref name=Rizzuto2011/> The visible component is a [[B-type main-sequence star]] with a [[stellar classification]] of B9V.<ref name=houk1979/>
