  • Epsilon Octantis, Latinized from ε Octantis, is a star in the southern circumpolar constellation of Octans. It is a faintly visible to the naked eye with an apparent visual magnitude of 5.09. The annual parallax shift of 11.22 mas yields a distance estimate of around 291 light years. It is moving further from the Sun with a radial velocity of +11.7 km/s. This is an evolved, cool red giant star with a stellar classification of class M5III. It is a semiregular variable with a magnitude range of 4.58 to 5.3 and a (poorly defined) period around 55 days. The star has 1.34 times the mass of the Sun and has expanded to around 112 times the Sun's radius. It is radiating 1,819 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 3,560 K. (en)

  • Epsilon Octantis (70 Octantis) é uma estrela na direção da constelação de Octans. Possui uma ascensão reta de 22h 20m 01.48s e uma declinação de −80° 26′ 22.7″. Sua magnitude aparente é igual a 5.09. Considerando sua distância de 268 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.51. Pertence à classe espectral M6III. (pt)
  • Epsilon Octantis (ε Octantis, förkortat Epsilon Oct, ε Oct) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den inre delen av stjärnbilden Oktanten. Den har en skenbar magnitud på 5,09 och är svagt synlig för blotta ögat. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 11,2 mas, beräknas den befinna sig på ett avstånd på ca 291 ljusår (ca 89 parsek) från solen. Den rör sig bort från solen med en radialhastighet på +11,7 km/s. (sv)
