== Nomenclature == ''ε Eridani'', [[Latinisation of names|Latinised]] to ''Epsilon Eridani'', is the star's [[Bayer designation]]. Despite being a relatively bright star, it was not [[List of proper names of stars|given a proper name]] by early astronomers. It has several other [[stellar designation|catalogue designations]]. Upon its discovery, the planet was designated Epsilon Eridani b, following the usual [[exoplanet naming convention|designation system for extrasolar planets]]. The planet and its host star were selected by the [[International Astronomical Union]] (IAU) as part of the [[NameExoWorlds]] competition for giving proper names to exoplanets and their host stars, for some systems that did not already have proper names.<ref name=nameexoworlds /><ref name=the_exoworlds /> The process involved nominations by educational groups and public voting for the proposed names.<ref name=exoworlds_process /> In December 2015, the IAU announced the winning names were ''Ran'' for the star and ''AEgir'' {{sic}} for the planet.<ref name=iau_results /> Those names had been submitted by the pupils of the [[School grades (US)|8th Grade]] at Mountainside Middle School in [[Colbert, Washington]], United States. Both names derive from [[Norse mythology]]: [[Rán]] is the goddess of the sea and [[Ægir]], her husband, is the god of the ocean.<ref name=NameExoworlds/> In 2016, the IAU organised a [[IAU Working Group on Star Names|Working Group on Star Names]] (WGSN)<ref name="WGSN">{{cite web | url=https://www.iau.org/science/scientific_bodies/working_groups/280/ | title=IAU Working Group on Star Names (WGSN)|access-date=May 22, 2016}}</ref> to catalogue and standardise proper names for stars. In its first bulletin of July 2016,<ref name="WGSN1">{{cite web | url=http://www.pas.rochester.edu/~emamajek/WGSN/WGSN_bulletin1.pdf | title=Bulletin of the IAU Working Group on Star Names, No. 1 |access-date=July 28, 2016}}</ref> the WGSN explicitly recognised the names of exoplanets and their host stars that were produced by the competition. Epsilon Eridani is now listed as Ran in the IAU Catalog of Star Names.<ref name="IAU-CSN" /> Professional astronomers have mostly continued to refer to the star as Epsilon Eridani.<ref name=ADS_HD_22049/> In [[Chinese astronomy|Chinese]], {{lang|zh|天苑}} ({{Transliteration|zh|Tiān Yuàn}}), meaning ''[[Hairy Head (Chinese constellation)|Celestial Meadows]]'', refers to an [[asterism (astronomy)|asterism]] consisting of ε Eridani, [[Gamma Eridani|γ Eridani]], [[Delta Eridani|δ Eridani]], [[Pi Eridani|π Eridani]], [[Zeta Eridani|ζ Eridani]], [[Eta Eridani|η Eridani]], [[Pi Ceti|π Ceti]], [[Tau1 Eridani|τ<sup>1</sup> Eridani]], [[Tau2 Eridani|τ<sup>2</sup> Eridani]], [[Tau3 Eridani|τ<sup>3</sup> Eridani]], [[Tau4 Eridani|τ<sup>4</sup> Eridani]], [[Tau5 Eridani|τ<sup>5</sup> Eridani]], [[Tau6 Eridani|τ<sup>6</sup> Eridani]], [[Tau7 Eridani|τ<sup>7</sup> Eridani]], [[Tau8 Eridani|τ<sup>8</sup> Eridani]] and [[Tau9 Eridani|τ<sup>9</sup> Eridani]].<ref>{{in lang|zh}} ''中國星座神話'', written by 陳久金.
