Gamma3 Octantis, Latinized from γ3 Octantis, is a solitary star in the southern circumpolar constellation Octans. It has an apparent magnitude of 5.283, making it faintly visible to the naked eye under ideal conditions. The star is situated at a distance of 264 light years but is receding with a heliocentric radial velocity of 15 km/s. Gamma3 Octantis has a classification of K1/2 III, displaying a blended spectrum of a K1 and K2 giant star that is on the horizontal branch. At present it has 2.23 times the mass of the Sun but has expanded to almost 10 times its girth. It shines at 50.5 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,879 K, which gives it a yellowish-orange glow. Gamma3 Octantis is metal enriched with an iron abundance 1.55 times that of the Sun and spins leisurely with a projected rotational velocity] less than 1 km/s, common for giant stars. (en) Gamma3 Octantis (1 Octantis) é uma estrela na direção da constelação de Octans. Possui uma ascensão reta de 00h 10m 02.27s e uma declinação de −82° 13′ 26.4″. Sua magnitude aparente é igual a 5.29. Considerando sua distância de 242 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.93. Pertence à classe espectral K1/K2III.
