The included article is well-known in astronomy. Many ancient star names were simply the name of an object, or the star's location in a constellation. During the dark ages, much of the knowledge of the sky was preserved by the Arabs who translated the meanings into Arabic. When the names were translated from Arabic back into European languages, the Arabic name was often used in part or in whole and the "al" was often included in the star name. Hence there are over 100 star names beginning in "al", all the way from Aladfar from "al Athfar" meaning "the talons" to Alzirr from "Al Zirr," meaning "the Button".
