- ο Ophiuchi, Latinized as Omicron Ophiuchi, is a wide double star in the equatorial constellation of Ophiuchus. The co-moving pair are visible to the naked eye as a dim point of light, with the two components having apparent visual magnitudes of 5.14 and 6.59. As of 2015, they had an angular separation of 10.0″ along a position angle of 354°. The distance to both stars is approximately 281 light years based on parallax, and they are drifting closer to the Sun with a radial velocity of around −29 km/s. The brighter member of the pair, designated component A, is an aging giant star with a stellar classification of G8III. With the supply of hydrogen at its core exhausted, it has expanded to 12 times the radius of the Sun. The star is radiating 75 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,849 K. The secondary star, component B, has a class of F6IV-V, matching an F-type star with a luminosity class that is a blend of traits from a main sequence and a subgiant star. It has three times the Sun's radius and is radiating 12.6 times the Sun's luminosity at 6,296 K. (en)
- Omikron Ophiuchi (ο Ophiuchi , förkortat Omikron Oph, ο Oph) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den södra delen av stjärnbilden Ormbäraren. Den har en skenbar magnitud på 5,2 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 11 mas, beräknas den befinna sig på ett avstånd av ca 290 ljusår (90 parsek) från solen. (sv)
- Omicron Ophiuchi (39 Ophiuchi) é uma estrela na direção da constelação de Ophiuchus. Possui uma ascensão reta de 17h 18m 00.72s e uma declinação de −24° 17′ 12.8″. Sua magnitude aparente é igual a 5.14. Considerando sua distância de 363 anos-luz em relação à Terra, sua magnitude absoluta é igual a −0.09. Pertence à classe espectral K:.... (pt)
