Alpheratz is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Arabic. It is the name of HIP 677 (α And, HR 15) in constellation And.

Etymology and History

The specific origin of this name is unclear. It may represent a transfer from β Peg, where alferaz and other variants were applied in medieval times as abbreviations for β Peg's Arabic name mankib al-faras, "the Horse's Shoulder". Or, it may be from an abbreviation of the name alpheraz id est equus, "alpheraz, that is, the Horse", which was applied directly to α And also in medieval times. In any case, Medieval Latin authors confused these two names, their spellings, and their identifications, and the modern application of "Alpheratz" to α And comes down to us from late medieval times.
