About: Theta Lyrae

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

Theta Lyrae (θ Lyr) is a star in a trinary star system, in the constellation Lyra, approximately 770 light years away from Earth. Theta Lyrae is an orange bright giant star of the spectral type K0II, which means that it possesses a surface temperature of about 5,000 kelvins, and is many times bigger and brighter, yet cooler, than the Sun.

dbo:abstract
  • Theta Lyrae (θ Lyr) is a star in a trinary star system, in the constellation Lyra, approximately 770 light years away from Earth. Theta Lyrae is an orange bright giant star of the spectral type K0II, which means that it possesses a surface temperature of about 5,000 kelvins, and is many times bigger and brighter, yet cooler, than the Sun. It is orbited by a subsystem composed of BD+37° 3399 and BD+37° 3399B. 10th magnitude BD+37° 3399 is a giant star with a spectral type of K2III. It is therefore almost the same temperature as Theta Lyrae, but smaller and dimmer. BD+37° 3399B is an 11th magnitude star of an unknown spectral type. (en)
  • Theta Lyrae ( θ Lyrae, förkortat Theta Lyr, θ Lyr) som är stjärnans Bayerbeteckning, är en trippelstjärna belägen i den östra delen av stjärnbilden Lyran. Den har en skenbar magnitud på 4,35 och är synlig för blotta ögat. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 4,2 mas, beräknas den befinna sig på ett avstånd av ca 770 ljusår (240 parsek) från solen. (sv)
  • Theta Lyrae (21 Lyrae) é uma estrela na direção da constelação de Lyra. Possui uma ascensão reta de 19h 16m 22.10s e uma declinação de +38° 08′ 01.4″. Sua magnitude aparente é igual a 4.35. Considerando sua distância de 769 anos-luz em relação à Terra, sua magnitude absoluta é igual a −2.51. Pertence à classe espectral K0II. (pt)
