6 Canis Minoris is a star in the equatorial constellation of Canis Minor, located around 570 light years away from the Sun. It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of +4.55. This object is moving closer to the Earth with a heliocentric radial velocity of −16.3 km/s. Kinematically, it is a member of an outlying group belonging to the Ursa Major flow of the Sirius supercluster.

This is an evolved giant star with a stellar classification of K1 III. It has a mild barium anomaly, which may indicate this is a binary star system with a white dwarf companion. The interferometry-measured angular diameter of the visible component is about {{Val|2.31|0.03|ul=mas}}, which, at its estimated distance, equates to a physical radius of about 44 times the radius of the Sun. This star has four times the mass of the Sun and is radiating 761 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,370 K.
