Location of υ Eridani stars (circled)
Some sources include the following stars:
- υ5 Eridani (f Eridani)
- υ6 Eridani (g Eridani)
- υ7 Eridani (h Eridani)
This series of stars bore the traditional proper names Theemim (also Theemin) and Beemin (also Beemim).[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 υ2 Eridani on 1 February 2017 and Beemim for υ3 Eridani on 30 June 2017; both are now included in the List of IAU-approved Star Names.[4]
