23 Orionis

23 Orionis is a double star located around 1,200 light-years (370 parsecs) away from the Sun in the equatorial constellation of Orion. It is visible to the naked eye as a dim, blue-white-hued point of light with a combined apparent visual magnitude of 4.99. The pair are moving away from the Earth with a heliocentric radial velocity of 18 km/s, and they are members of the Orion OB1 association, subgroup 1a.

Howe and Clarke (2009) catalog this as a double-lined spectroscopic binary star system with a wide projected separation of 9,460 AU. As of 2018, they had an angular separation of 31.9″ along a position angle of 30°. The brighter member, component A, is a B-type main-sequence star with a stellar classification of B1V. The secondary, component B, is of class B3V. Both stars are spinning rapidly.
