HD 125628 is a binary star [3] system in the constellation Centaurus. It is faintly visible to the naked eye with a combined apparent visual magnitude of 4.76. [2] The distance to this system is approximately 380 light years based on parallax. It is drifting further away from the Sun with a radial velocity of +15 km/s. [2] The absolute magnitude is −0.55. [2]
The primary component of this system, component A, is an aging giant star with a stellar classification of G9III [3] and a visual magnitude of 5.09. [3] The secondary companion, designated component B, is a magnitude 6.94 [3] star located at an angular separation of 9.10 ″ from the primary, along a position angle of 157°, as of 2016. [6] It is an F-type main-sequence star with a class of F5V. [3]
