Eta Eridani (η Eridani, abbreviated Eta Eri, η Eri), officially named Azha (with a silent 'h', possibly / ˈ eɪ z ə /), [8] [7] is a giant star in the constellation of Eridanus. Based on parallax measurements taken during the Hipparcos mission, it is approximately 137 light-years from the Sun .
It is an evolved red clump [12] giant star with a stellar classification of G8+ III. [3] The measured angular diameter is 2.21 mas. [13] At the star's distance, this yields a physical size of around 16 times the radius of the Sun. [6] It radiates 138 [7] times the solar luminosity from its outer atmosphere at an effective temperature of 5074 K. [8]
Tau Eridani (τ Eridani, τ Eri) is a group of fairly widely scattered stars in the constellation Eridanus. τ 1 Eridani (1 Eridani) [1] τ 2 Eridani (2 Eridani) [2] τ 3 Eridani (11 Eridani) [3] τ 4 Eridani (16 Eridani) [4] τ 5 Eridani (19 Eridani) [5] τ 6 Eridani (27 Eridani) [6] τ 7 Eridani (28 Eridani) [7] τ 8 Eridani (33 Eridani) [8 ...
[1] [2] In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) [3] to catalog and standardize proper names for stars. The WGSN approved the names Theemin for υ 2 Eridani on 1 February 2017 and Beemim for υ 3 Eridani on 30 June 2017; both are now included in the List of IAU-approved Star Names. [4]
EK Eridani is a single variable star [4] in the equatorial constellation of Eridanus. [2] It has the designation HR 1362 from the Bright Star Catalogue; EK Eridani is the variable star designation, abbreviated EK Eri. This star is dimly visible to the naked eye with a brightness that fluctuates around 6.15. [2]
Tau 3 Eridani, Latinized from τ 3 Eridani, is a star in the constellation Eridanus.It is visible to the naked eye with an apparent visual magnitude of 4.10. [2] Using the parallax method, [1] the distance to this star can be estimated as 88.6 light years.
In the southern-sky catalog Uranometria Argentina, 82 G. Eridani (often abbreviated to 82 Eridani) [9] is the 82nd star listed in the constellation Eridanus. [10] The Argentina catalog, compiled by the 19th-century astronomer Benjamin Gould, is a southern celestial hemisphere analog of the more famous Flamsteed catalog, and uses a similar numbering scheme. 82 G. Eridani, like other stars near ...
