''ζ Aurigae'' ([[Latinisation of names|Latinised]] to ''Zeta Aurigae'') is the system's [[Bayer designation]]. The designations of the two components as ''ζ Aurigae A'' and ''B'' derive from the convention used by the Washington Multiplicity Catalog (WMC) for [[Star system|multiple star system]]s, and adopted by the [[International Astronomical Union]] (IAU).<ref name="planetnaming"/>
The system bore the traditional names ''Haedus I'' (also ''Hoedus'') and ''Sadatoni'' (rarely ''Saclateni'').<ref name=Rumrill/> It was one of the two ''haedi'' ([[Latin]]: 'kids') of the she-goat [[Capella]], the other being Haedus II, [[Eta Aurigae]]. The name Sadatoni is from the [[Arabic]] الساعد الثاني ''as-sā<sup>c</sup>id aθ-θānī'' "the second arm (of the charioteer)". The rare traditional name ''Azaleh'' is shared (in the form ''Hassaleh'') with [[Iota Aurigae]].<ref name=kaler/> In 2016, the IAU organized a [[IAU Working Group on Star Names|Working Group on Star Names]] (WGSN)<ref name="WGSN"/> to catalog and standardize proper names for stars. The WGSN decided to attribute proper names to individual stars rather than entire [[multiple star|multiple systems]].<ref name="TriRpt18"/> It approved the names ''Saclateni'' for the component Zeta Aurigae A and ''Haedus'' for [[Eta Aurigae]] on 30 June 2017 and they are both now so included in the List of IAU-approved Star Names.<ref name="IAU-LSN"/>
In [[Chinese astronomy|Chinese]], {{lang|zh|柱}} ({{lang|zh-Latn|Zhù}}), meaning ''[[Net (Chinese constellation)|Pillars]]'', refers to an [[Asterism (astronomy)|asterism]] consisting of Zeta Aurigae, [[Epsilon Aurigae]], Eta Aurigae, [[Upsilon Aurigae]], [[Nu Aurigae]], [[Tau Aurigae]], [[Chi Aurigae]] and [[26 Aurigae]].<ref name=zh/> Consequently, the [[Chinese star names|Chinese name]] for Zeta Aurigae itself is {{lang|zh|柱二}} ({{lang|zh-Latn|Zhù èr}}, {{
