Mesarthim doesn't look like Sanskrit to me; I'd be amazed if the meaning "first star in Aries" could be packed into three syllables in such a language. Richard Hinckley Allen Star-Names and Their Meanings (1899) says it "has been connected with the Hebrew Məshãrətĩm, Ministers, but the connection is not apparent; and Ideler considered the word an erroneous deduction by Bayer from the name of the lunar station of which this and β were members," but I can't find anything in Allen about the latter. —Tamfang (talk) 19:49, 17 March 2008 (UTC)
The 12th century Rabbi, astronomer and astrologer Abraham Ibn Ezra consistently uses the word meshartim (ministers) for planets. This is an idiosyncracy of his, as this usage is not widespread even in his time. Ibn Ezra was exceptionally influential in spreading Arabic astronomy in the Latin west, usually first through hebrew. There is a crater on the moon named after him, which makes it plausible that this star also has been named after his terminology. However, he used the term only for planets, not stars, which confuses the matter somewhat. For Ibn Ezra's use of the term, see the works of Shlomo Sela: Abraham ibn Ezra and the Rise of Medieval Hebrew science (Brill 2003) and his trasnlations of Ibn Ezra's Book of the World (Brill 2010) and Book of Reasons (Brill 2007). —Preceding unsigned comment added by 184.108.40.206 (talk) 09:09, 12 March 2011 (UTC)
The main article says that Gamma Arietis is at a distance of 204 light-years, but the sidebar gives the distance as 160 light-years, or fifty parsecs.
They can't both be right.
