Eridanus is depicted in ancient sky charts as a flowing river, starting from Orion and flowing in a meandering fashion past Cetus and Fornax and into the southern hemispheric stars. Johann Bayer's Uranometria depicts the river constellation as a flowing river.
Epsilon Eridani is located in the northern part of the constellation Eridanus, about 3° east of the slightly brighter star Delta Eridani. With a declination of −9.46°, Epsilon Eridani can be viewed from much of Earth's surface, at suitable times of year.
Upsilon 2 Eridani (υ² Eridani, abbreviated Upsilon 2 Eri, υ 2 Eri), officially named Theemin / ˈ θ iː m ə n /, [10] [11] is a star in the constellation of Eridanus. It is visible to the naked eye with an apparent visual magnitude of 3.8. [2]
Delta Eridani, which is Latinized from δ Eridani, is the fifth-brightest star in the constellation of Eridanus.. The star is visible to the naked eye and has been observed to vary slightly in brightness between magnitudes 3.51 and 3.56, [2] although subsequent observations did not bear this out. [11]

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 ...
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
