Dit gee Gamma Aquarii die tipiese wit kleur van ’n A-tipe ster.

==Name==
Die ster se [[Bayer-naam]] is "Gamma Aquarii" en sy [[Flamsteed-naam]] "48&nbsp; Aquarii". WDS&nbsp;J22217-0123&nbsp;A is sy naam in die Washington Double Star Catalog. Die tradisionele naam, "Sadachbia", kom van die [[Arabies]]e uitdrukking سعد الأخبية ''sa‘d al-’axbiyah'', "geluk van die huise (tente)". 

In 2016 het die [[Internasionale Astronomiese Unie]] se sternaamwerkgroep (WGSN) die naam "Sadachbia" vir die komponent WDS&nbsp;J22217-0123&nbsp;Aa goedgekeur<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 |accessdate=28 Julie 2016}}</ref> omdat hulle eiename aan individuele sterre toegeken het eerder as aan stergroepe.
