About: Theta Sagittae

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

Theta Sagittae (θ Sagittae) is a double star in the northern constellation of Sagitta. With a combined apparent visual magnitude of +6, it is near the limit of stars that can be seen with the naked eye. According to the Bortle scale the star is visible in dark suburban/rural skies. Based upon an annual parallax shift of 22.15 mas as seen from Earth, it is located roughly 147 light years from the Sun.

  • Theta Sagittae (en abrégé the Sge ou θ Sge) est la désignation de Bayer d'une étoile de la constellation de la Flèche, située à environ 20h 09m 56,647s d'ascension droite et +20° 54′ 54,10″ de déclinaison. Il s'agit d'une sous-géante (classe de luminosité IV) jaune-blanc (type spectral F). (fr)
  • Theta Sagittae (θ Sagittae) is a double star in the northern constellation of Sagitta. With a combined apparent visual magnitude of +6, it is near the limit of stars that can be seen with the naked eye. According to the Bortle scale the star is visible in dark suburban/rural skies. Based upon an annual parallax shift of 22.15 mas as seen from Earth, it is located roughly 147 light years from the Sun. The binary pair consists of two stars separated by 502 AU. The primary, component A, is an F-type main sequence star with a stellar classification of F3V. This star is about two billion years old with 52% more mass than the Sun. It forms a double star with a magnitude 8.85 companion, which is located at an angular separation of 11.58 arc seconds along a position angle of 331.1°, as of 2011. The star is sometimes described as a triple star, with a 7th magnitude companion 91″ away. This is an unrelated giant star much further away than the close pair. A fainter star separated by nearly 3′ was also listed as a companion by Struve, again just an accidental optical association. (en)
  • Theta Sagittae (17 Sagittae) é uma estrela na direção da constelação de Sagitta. Possui uma ascensão reta de 20h 09m 56.61s e uma declinação de +20° 54′ 53.2″. Sua magnitude aparente é igual a 6.51. Considerando sua distância de 147 anos-luz em relação à Terra, sua magnitude absoluta é igual a 3.24. Pertence à classe espectral F5IV. (pt)
  • Theta Sagittae (θ Sagittae, förkortat Theta Sge, θ Sge) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den nordöstra delen av stjärnbilden Pilen. Den har en skenbar magnitud på 6,48 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 22,2 mas, beräknas den befinna sig på ett avstånd av ca 147 ljusår (ca 45 parsek) från solen. (sv)
