67 Ophiuchi (67 Oph) is a class B5 Ib[3] (blue supergiant) star in the constellation Ophiuchus. Its apparent magnitude is 3.93[2] and it is approximately 2,000 light years away based on spectroscopy.[5] It is considered to be a member of the open cluster Collinder 359 (Melotte 186).
67 Oph has four companions. The closest is a magnitude 13.7 B1 main sequence star at 8.29", designated B. Component C (BD+02°3459) is the brightest close companion, a magnitude 8.1 B2 main sequence star at 54.32". Component D is a magnitude 12.5 star 8.37" from component C. Component E is a magnitude 10.9 star 46.53" from 67 Oph A.[9]
This star was once considered part of the obsolete constellation Taurus Poniatovii, but after the International Astronomical Union officially recognized constellations, it was placed in Ophiuchus.[10]
