IAU name adopted: 2016-08-21

Name origin (IAU): The formation of this name begins with the Arabic lunar mansion name al-sharatan, for β and γ Ari. From the numerous medieval lists of the Arabic lunar mansions (all in Latin transliteration), the Early Modern scholar Johannes Bayer grasped the form Sartai, and used it for the three brighter stars α, β and γ Ari. Bayer also erroneously explained Sartai as from the Hebrew word mesharethim, "servants", rather than from al-sharatan. Subsequently, Bayer's erroneous word, written as "Mesarthim", was applied as a star name.

Constellation

At magnitude 4.8 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
Declination 19.3° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
Its IAU name «Mesarthim» comes from Arabic (IAU Working Group on Star Names).
