			The famous M-type supergiant variable star designated µ Cephei has two proper names listed in SIMBAD as of 2024: "Erakis" and "Herschel's Garnet Star". Both terms are incorrect, as Herschel did not name this star and "Erakis" is an uncommon transliteration variant of a star name that is applied somewhere else. The IAU WGSN, therefore, decided to drop this name for the IAU-CSN.

	==Etymology and History==		==Etymology and History==
	The etymology of "Erakis" is shared with the name "Alrakis", which WGSN already adopted for the star Mu Draconis A. Becvar appears to have mistakenly attributed a variant of the name (Erakis) to Mu Cephei instead of Mu Draconis~~, and no~~ evidence for association of the name with Mu Cephei has been found in pre-Becvar works. Becvar's name "Erakis" and association with Mu Cephei only appeared rarely in subsequent works (e.g. Rhoads 1971, Bakich 1995).		The etymology of "Erakis" is shared with the name "Alrakis", which WGSN already adopted for the star µ Draconis A. Kunitzsch and Smart (2006) translate الراقص, ''ar-rāqiṣ'', "the Trotting Camel." It forms part of an asterism in the Arabian sky. Transliteration (Romanization) from Arabic could be Arrakis or Alrakis, in English the latter variant is more common.

			However, in some dialects of Arabic, e.g. in the Maghreb (northwest African areas), the "a" is not pronounced as a diphthong, and as there French is the second official language, people Romanize the Arabic letter "aleph" (ا) not with (French) "a" but with "e" (to be distinguished from French è and é). Hence, the variant Er(r)akis may also be valid, although not standard.
