Rho3 Eridani, Latinized from ρ3 Eridani, is a star located in the constellation Eridanus. It forms an asterism with Rho1 and Rho2 Eridani, south of Cetus, in the upper north east portion of Eridanus. The star has an apparent visual magnitude of 5.26, which is bright enough to be seen with the naked eye on a dark, clear night. The distance to this star, as determined via the parallax method, is about 136 light years.

  • Rho3 Eridani (ρ3 Eridani, förkortat Rho3 Eri, ρ3 Eri) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den nordvästra delen av stjärnbilden Eridanus. Den har en skenbar magnitud på 5,26, är svagt synlig för blotta ögat där ljusföroreningar ej förekommer och bildar en asterism med stjärnorna Rho1 och Rho2 Eridani, söder om Cetus. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 24,1 mas, beräknas den befinna sig på ett avstånd på ca 136 ljusår (ca 42 parsek) från solen. (sv)
  • Rho3 Eridani (10 Eridani) é uma estrela na direção da constelação de Eridanus. Possui uma ascensão reta de 03h 04m 16.48s e uma declinação de −07° 36′ 03.2″. Sua magnitude aparente é igual a 5.26. Considerando sua distância de 140 anos-luz em relação à Terra, sua magnitude absoluta é igual a 2.09. Pertence à classe espectral A8V. (pt)

  • Rho3 Eridani, Latinized from ρ3 Eridani, is a star located in the constellation Eridanus. It forms an asterism with Rho1 and Rho2 Eridani, south of Cetus, in the upper north east portion of Eridanus. The star has an apparent visual magnitude of 5.26, which is bright enough to be seen with the naked eye on a dark, clear night. The distance to this star, as determined via the parallax method, is about 136 light years. This is an A-type main sequence star with a stellar classification of A5 V. (Some sources list it as A8 V.) It is some 500 million years old and is spinning rapidly with a projected rotational velocity of 186 km/s. This rotation is giving the star a slightly oblate shape, with the equator being 5% larger than the poles. The star has about 120% of the radius of the Sun, and 183% of the Sun's mass. It shines with 10 times the solar luminosity from its outer atmosphere at an effective temperature of 7,400 K. (en)
