Gamma Canis Minoris

Gamma Canis Minoris is a binary star system in the equatorial constellation Canis Minor. Its name is a Bayer designation that is Latinized from γ Canis Minoris, and abbreviated Gamma CMi or γ CMi. The orange colour is obvious when seen through binoculars. The system is visible to the naked eye with a combined apparent visual magnitude of +4.33. Based upon an annual parallax shift of as seen from Earth, this system is located at a distance of approximately from the Sun. It is drifting further away with a line of sight velocity of 47 km/s.
This spectroscopic binary star system has an orbital period of 389.31 days, a semimajor axis of 1.48 AU, and an eccentricity of 0.2586. Their variable radial velocity was discovered by H. M. Reese in 1902 at Lick Observatory. Both components are evolved, K-type giant stars, most likely on their first ascent along the red giant branch. The primary, component A, has a stellar classification of K4 III while the secondary, component B, may be K1: III.
