Editing Beta Scorpii (section)

==Nomenclature==

''β Scorpii'' ([[Latinisation of names|Latinised]] to ''Beta Scorpii'') is the star's [[Bayer designation]]; ''β¹'' and ''β² Scorpii'', those of its two components. The designations of the sub-components - ''β Scorpii A'', ''Aa'', ''Ab'', ''B'', ''C'', ''E'', ''Ea'' and ''Eb'' - derive from the convention used by the Washington Multiplicity Catalog (WMC) for [[multiple star system]]s, and adopted by the [[International Astronomical Union]] (IAU).<ref name="planetnaming"/>

Beta Scorpii bore the traditional names ''Acrab'', ''Akrab'' or ''Elacrab'', all deriving from the [[Arabic]] name ({{langx|ar|العقرب}}) ''al-'Aqrab'' 'the Scorpion' for the whole constellation, as well as '''Graffias''' {{IPAc-en|'|g|r|æ|f|i|@|s}},<ref name=Davis44>{{cite journal

In 2016, the [[International Astronomical Union]] organized a [[IAU Working Group on Star Names|Working Group on Star Names]] (WGSN)<ref name="WGSN"/> to catalogue and standardize proper names for stars.
