γ 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: seen best with the naked eye). They are collectively called The Sickle. These stars form the top of the mane and Leo's face.

Gamma Leonis is a fine double (Struve 1424) of two yellow stars, with a much wider second companion:
      AB: 2.4, 3.6; 126º, 4.5". It has an orbit of 618.6 years.
      AC: 2.3, 9.6; 288º, 336.0".

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

Just north of delta is a fine binary 54 Leonis, a yellow primary and blue companion: 4.5, 6,3; 112º, 6.7".
