Two of the components (HD 126128) form a binary star system with an orbital period of 39.5 years and an eccentricity of 0.25. The third component (HD 126129), and the brightest member of the trio, lies at an angular separation of 6.250″ from the other two.[4] References1. ^1 {{Cite journal| doi = 10.1134/S1063773706110065| bibcode=2006AstL...32..759G| title = Pulkovo Compilation of Radial Velocities for 35 495 Hipparcos stars in a common system| journal = Astronomy Letters| volume = 32| issue = 11| pages = 759–771| date = November 2006| last1 = Gontcharov | first1 = G.
