About: Iota Ophiuchi

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

ι Ophiuchi, Latinized as Iota Ophiuchi, is a single star in the equatorial constellation of Ophiuchus, positioned near the constellation border with Hercules. It makes a naked-eye double with nearby Kappa Ophiuchi, appearing as a faint, blue-white hued star with an apparent visual magnitude of 4.39. The star is approximately 245 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −19 km/s.

  • ι Ophiuchi, Latinized as Iota Ophiuchi, is a single star in the equatorial constellation of Ophiuchus, positioned near the constellation border with Hercules. It makes a naked-eye double with nearby Kappa Ophiuchi, appearing as a faint, blue-white hued star with an apparent visual magnitude of 4.39. The star is approximately 245 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −19 km/s. This object is a B-type main-sequence star with a stellar classification of B8V. It is an estimated 217 million years old with a moderately high rate of spin, showing a projected rotational velocity of 124 km/s. The star has 3.1 times the mass of the Sun and around 2.8 times the Sun's radius. Iota Ophiuchi is radiating 141 times the luminosity of the Sun from its photosphere at an effective temperature of 11,220 K. It displays an infrared excess, suggesting the presence of circumstellar material. (en)
  • Iota Ophiuchi (25 Ophiuchi) é uma estrela na direção da constelação de Ophiuchus. Possui uma ascensão reta de 16h 54m 00.50s e uma declinação de +10° 09′ 55.6″. Sua magnitude aparente é igual a 4.39. Considerando sua distância de 234 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.11. Pertence à classe espectral B8V. (pt)
  • Jota Ophiuchi (ι Ophiuchi , förkortat Jota Oph, ι Oph) som är stjärnans Bayerbeteckning, är en stjärna belägen i den norra delen av stjärnbilden Ormbäraren. Den har en skenbar magnitud på 4,39 och är synlig för blotta ögat. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 13,3 mas, beräknas den befinna sig på ett avstånd av ca 245 ljusår (75 parsek) från solen. (sv)
