Zeta Canis Minoris (ζ Canis Minoris) is a solitary,[9] blue-white hued star in the equatorial constellation of Canis Minor. It is a dim star but visible to the naked eye with an apparent visual magnitude of 5.13.[2] Based on an annual parallax shift of 5.23 mas as seen from Earth,[1] this star is located around 410 light years from the Sun. It is moving away from the Sun with a radial velocity of +32.3 km/s.[4]

This is a B-type bright giant star with a stellar classification of B8 II.[3] It is a Mercury-Manganese star, showing an overabundance of these elements in its spectrum. The mean longitudinal magnetic field strength is 8.28±11.55 G.[10] The star has about four times the mass of the Sun and is radiating 490[6] times the Sun's luminosity from its photosphere at an effective temperature of 13,500 K.[7]
