Description of the Star

Algeiba B is a G7III giant separated from Algeiba A by 4.581 arc seconds and about one magnitude dimmer than Algeiba A. The separation of the two stars is 176 AU or more, that is more than 4 times the radius of the solar system out to Pluto. The period of the orbit of the orbit of the two stars about their common center of mass is a few hundred years.

The spectral type implies an effective temperature of about 4800 K, a diameter about 12 times that of the sun, and a mass about 3.5 times that of the sun. This implies a luminosity about 6 times that of the sun.
