It is too faint to be visible to the naked eye, having a combined apparent visual magnitude of 7.80.[2] The distance to this system is approximately 337 light years based on parallax, and it is receding from the Sun with a radial velocity of +10 km/s.[2] It is a member of the Lower Centaurus–Crux group of the Scorpius–Centaurus OB association of co-moving stars.[3]

This is a double-lined spectroscopic binary system consisting of two F-type main-sequence stars with similar masses and a matching stellar classification of F5 V.[1] Their orbital period is less than 100 days.[3]

Edge-on disc of gas and dust present around the binary star system HD 106906

A distant circumbinary planet—HD 106906 b—is orbiting the pair at a projected separation of Шаблон:Val with a period of at least 3,000 years. An infrared excess around the binary is coming from a circumstellar debris disk that is being viewed edge-on. This has a pronounced asymmetrical shape, extending 120 AU on the east side and out to 550 AU to the west.[3] Planetary orbit is inclined to the debris disk by 39Шаблон:± degrees, and planet itself is visible nearly pole-on, having a large axial tilt.[4] Шаблон:OrbitboxPlanet begin Шаблон:OrbitboxPlanet disk Шаблон:OrbitboxPlanet Шаблон:Orbitbox end
