Names For This Star

The name of this star is also written as "Algeiba" or "Al Gieba". The name would seem to derive from the Arabic name "Al Jebbah", meaning "The Forehead".

The position of Algieba lies on the mane of Leo, as the Lion is traditionally visualized. Since the Latin word for mane is Juba, Allen suggests that name of the star actually derives from Latin and became arabicized as a result of a misunderstanding or typographical error.

Description of the Star

Algeiba is a double star, described by Burnham as one of the finest double stars in the sky, although the pair is very close and difficult for low power telescopes to resolve.

Algeiba A is a yellow-orange early K type giant, K0III. This implies an effective temperature of 4500 K. The star should be 16 times larger than the sun in diameter, about 4 times larger in mass, and about 80 times as luminous as the sun.
