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

Omicron Cephei, Latinized from ο Cephei, is a binary star in the constellation of Cepheus. It consists of a less massive F-type main sequence star in orbit with a more massive G-type giant star. The overall apparent visual magnitude of the system is 4.75. The pair was first determined to be binary by F. G. W. Struve in 1832. Since then, the secondary has been seen to revolve approximately 45 degrees around the primary. A number of orbits have been computed, the most recent giving a period of approximately 1500 years.

  • Omicron Cephei (Omicron Cep, ο Cephei, ο Cep) adalah bintang biner yang terletak di rasi bintang Cepheus. Terdiri dari bintang dengan klasifikasi tipe K (bintang berukuran kecil) pada orbit dengan bintang raksasa (tipe G). [[Magnitudo semunya secara umum 4.75. (in)
  • Omikron Cephei (ο Cephei, förkortat Omikron Cep, ο Cep), som är stjärnans Bayer-beteckning, är en dubbelstjärna i den mellersta delen av stjärnbilden Cepheus. Den har en kombinerad skenbar magnitud på +4,75 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätningar i Hipparcos-uppdraget på 15,5 mas beräknas den befinna sig på ca 211 ljusårs (65 parsek) avstånd från solen. (sv)
  • Omicron Cephei (34 Cephei) é uma estrela tripla na direção da constelação de Cepheus. Possui uma ascensão reta de 23h 18m 37.41s e uma declinação de +68° 06′ 41.1″. Sua magnitude aparente é igual a 4.75. Considerando sua distância de 211 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.70. Pertence à classe espectral K0III. (pt)
