Bintang ini dikenal dengan nama '''The Persian''' (orang Persia), nama yang diberikan oleh pendeta [[Jesuit]] pada abad ke 17. Nama ini merupakan mistranslasi dari nama rasi ''Indus'' berasal dari nama salah satu asterisma dimana bintang ini berada, yaitu ''Pe Sze'' 波斯 "orang Persia" (sebagai bintang kedua). Nama yang diberikan oleh [[bangsa Arab]] untuk bintang ini adalah ''Al Nair,'' dari النائر ''an-na´ir'' "yang terang", nama yang dibagi dengan [[Alpha Gruis]]. |
