HD 125288 is a single[8] star in the southern constellation of Centaurus. It has the Bayer designation v Centauri (lower case V); while HD 125288 is the star's identifier in the Henry Draper catalogue. The object has a blue-white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.30.[1] Based on spectroscopic measurements, it is located at a distance of approximately 1,270 light years from Earth.[6] This is a candidate runaway star that is moving to the west and falling back into the Galactic plane.[5] It has an absolute magnitude of −3.56.[1]

This massive B-type supergiant star[3] has a stellar classification of B5Ib/II[4] or B6Ib.[5] It is around 29 million years old and has 9 times the mass of the Sun. The star has expanded to 21 times the girth of the Sun and is spinning with a projected rotational velocity of 23 km/s. It is radiating 12,600 times the luminosity of the Sun from its photosphere at an effective temperature of 13,700 K.[6]

In 2016, an asterism including HD 125288 (SAO 241641) was unofficially identified in honor of David Bowie.[9][10]
