Eta1 Doradus, Latinized from η1 Doradus, is a star in the southern constellation of Dorado. It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 5.72. [2] This object is located approximately 335 light years distant from the Sun, based on parallax, and is drifting further away with a radial velocity of +18 km/s. [2] It is circumpolar south of latitude 24°S.
This object is an A-type main-sequence star with a stellar classification of A0V. [3] It is 94 [5] million years old with a high rotation rate, showing a projected rotational velocity of 149. [5] The star has 2.46 [5] times the mass of the Sun and is radiating 49 [6] times the Sun's luminosity from its photosphere at an effective temperature of 10,325 K. [7] It is the southern pole star of Venus. [9]
