g Leonis


Gamma Leonis, "Algeiba" (perhaps erroneously, as the name means 'The Forehead'). Flamsteed and others in the seventeenth and eighteenth century called the star Juba, 'mane', a much more sensible designation.

Gamma is eight degrees north of alpha Leonis, and slightly to the east. In the same field of view is zeta: binoculars.

The stars to the west of zeta (mu, epsilon, lambda, and kappa: binoculars) are collectively called The Sickle. These stars form the top of the mane and Leo's face.

Gamma Leonis is a fine double (gamma1 and gamma2) with an orbit of 618 years. At J2000.0 (1 January 2000) the companion will be at a position angle of 125º and separation 4.4"

To the east of gamma is delta Leonis, Zosma, which once had a better name, Duhr, meaning the Lion's Back.
