Eta Circini, Latinized from η Circini, is the Bayer designation for a solitary star located in the southern constellation of Circinus. It is faintly visible to the naked eye with an apparent visual magnitude of 5.17. The distance to this star, as determined from an annual parallax shift of 11.82 mas, is around 276 light years. This is an evolved G-type giant star with a stellar classification of G8 III. It is radiating an estimated 64 times the solar luminosity from its outer atmosphere at an effective temperature of 4,954 K.

  • Eta Circini (η Circini, förkortat, Eta Cir, η Cir), som är stjärnans Bayer-beteckning, är en ensam stjärna med en skenbar magnitud på 5,17 i Cirkelpassarens stjärnbild och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 11,8 mas, beräknas den befinna sig på ett avstånd på ca 276 ljusår (ca 85 parsek) från solen. (sv)
  • Eta Circini (n Cir, n Circini) é uma estrela na constelação de Circinus. Tem uma magnitude aparente visual de 5,17, sendo visível a olho nu em boas condições de visualização. Sua distância da Terra, calculada a partir da sua paralaxe, é de aproximadamente 274 anos-luz (83,8 parsecs). É uma estrela gigante de classe G com tipo espectral de G8 III e temperatura efetiva de 5 038 K, portanto tem coloração amarela. É uma das estrelas observadas pela sonda Hipparcos com a menor variação de magnitude, de apenas 0,0005. Não possui estrelas companheiras conhecidas. (pt)
  • Эта Циркуля (англ. Eta Circini, η Cir), η Циркуля — одиночная звезда в южном созвездии Циркуля. Звезда слабо видна невооружённым глазом, видимая звёздная величина равна 5,17. Расстояние до звезды, определённое на основе измерения параллакса (11,82 мсд),составляет около 276 световых лет. Эта Циркуля представляет собой звезду-гигант спектрального класса G (G8 III) на поздней стадии эволюции. Светимость в 64 раза превышает солнечную, эффективная температура внешних слоёв атмосферы составляет 4954 K. (ru)
