HD 111597 is a suspected astrometric binary[9] 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.[1] It is located at a distance of approximately 410 light years from the Sun based on parallax,[2] and has an absolute magnitude of −0.53.[1] The system is a probable member of the Sco OB2 association of co-moving stars.[10] The visible component is a B-type main-sequence star with a stellar classification of B9V.[3]
