Epsilon Doradus (ε Doradus, förkortat Epsilon Dor, ε Dor) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den södra delen av stjärnbilden Svärdfisken. Den har en skenbar magnitud på 5,11 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 5,7 mas, beräknas den befinna sig på ett avstånd på ca 570 ljusår (ca 176 parsek) från solen. På detta avstånd minskar stjärnans skenbara magnitud med 0,09 enheter genom en skymningsfaktor beroende på interstellärt stoft. Epsilon Doradus (34 Doradus) é uma estrela na direção da constelação de Dorado. Possui uma ascensão reta de 05h 49m 53.55s e uma declinação de −66° 54′ 04.4″. Sua magnitude aparente é igual a 5.10. Considerando sua distância de 512 anos-luz em relação à Terra, sua magnitude absoluta é igual a −0.88. Pertence à classe espectral B6V. Epsilon Doradus, Latinzied from ε Doradus, is a solitary star located in the southern constellation of Dorado. It is visible to the naked eye with an apparent visual magnitude of 5.11. Based upon an annual parallax shift of 5.68 mas as measured from Earth, it is located roughly 570 light years from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction factor of 0.09 due to interstellar dust. 劍魚座ε，又名CP-66 463，HD 39844、SAO 249368、HR 2064，是劍魚座的一颗恒星，视星等为5.11，位于銀經276.8，銀緯-30.8，其B1900.0坐标为赤經5h 49m 59.8s，赤緯-66° -30.8′ 34″。

dbo:abstract
Epsilon Doradus, Latinzied from ε Doradus, is a solitary star located in the southern constellation of Dorado. It is visible to the naked eye with an apparent visual magnitude of 5.11. Based upon an annual parallax shift of 5.68 mas as measured from Earth, it is located roughly 570 light years from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction factor of 0.09 due to interstellar dust. This is a B-type main sequence star with a stellar classification of B6 V. It is a slowly pulsating B-type star with a mean longitudinal magnetic field strength of −64±26 G. With 4.31 times the mass of the Sun and 3.8 times the Sun's radius, it is about 85% of the way through its main sequence lifetime. The star is an estimated 210 million years old and is spinning with a projected rotational velocity of 17 km/s. Epsilon Doradus radiates 556 times the solar luminosity from its photosphere at an effective temperature of 13,212 K. Epsilon Doradus (ε Doradus, förkortat Epsilon Dor, ε Dor) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den södra delen av stjärnbilden Svärdfisken. Den har en skenbar magnitud på 5,11 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 5,7 mas, beräknas den befinna sig på ett avstånd på ca 570 ljusår (ca 176 parsek) från solen. På detta avstånd minskar stjärnans skenbara magnitud med 0,09 enheter genom en skymningsfaktor beroende på interstellärt stoft. Epsilon Doradus (34 Doradus) é uma estrela na direção da constelação de Dorado. Possui uma ascensão reta de 05h 49m 53.55s e uma declinação de −66° 54′ 04.4″. Sua magnitude aparente é igual a 5.10.
