Star in the constellation Centaurus
HD 111597 is a suspected
astrometric binary
[7] 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.
[2] It is located at a distance of approximately 380
light years from the
Sun based on
parallax ,
[1] and has an
absolute magnitude of −0.53.
[2] The system is a probable member of the
Sco OB2 association of co-moving stars.
[8] The visible component is a
B-type main-sequence star with a
stellar classification of B9V.
