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]
