SIMBAD data

3 Monocerotis is a binary star [3] system in the equatorial constellation of Monoceros, located approximately 780 light years away from the Sun based on parallax. [1] It is visible to the naked eye as a faint, blue-white hued star with a combined apparent visual magnitude of 4.92. [2] The system is moving further from the Earth with a heliocentric radial velocity of +39 km/s. [6]

The magnitude 4.98 primary, designated component A, has a stellar classification of B5 III, [4] matching an evolved blue giant star. It has 5.85 [9] times the mass of the Sun and is radiating 1,105 [2] times the Sun's luminosity from its photosphere at an effective temperature of 15,000 K. [9] The companion, component B, is magnitude 7.96 with an angular separation of 1.9″ from the primary. [14]
