The designations of the two components as Xi Aquarii A and B derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU). [11] Along with Beta Aquarii (Sadalsuud) it constituted the Persian lunar mansion Bunda. [12]
α Aquarii (Latinised to Alpha Aquarii) is the star's Bayer designation.WDS J22058-0019 A is its designation in the Washington Double Star Catalog..
