Zeta Monocerotis, Latinized from ζ Monocerotis, is a single, [9] yellow-hued star in the constellation Monoceros. It has an apparent visual magnitude of 4.33, [2] which is bright enough to be visible to the naked eye. The annual parallax shift as measured during the Hipparcos mission is 3.08  milliarcseconds, [1] which provides a rough distance estimate of 1,060  light years. It is moving away from the Sun with a radial velocity of +30 km/s. [4]

This star has a stellar classification of G2 Ib, [3] which matches a supergiant of type G. It has an estimated 6.2 [6] times the mass of the Sun and is radiating 2,207 [5] times the Sun's luminosity from its photosphere at an effective temperature of 5,289 K. [8] Zeta Monocerotis has three visual companions: component B, with separation 33.3" and magnitude 10.32, C, with separation 65.1" and magnitude 9.68, and D, with separation 38.1" and magnitude 13.4.
