32 Orionis

32 Orionis is a triple star system in the equatorial constellation of Orion. It has the Bayer designation A Orionis, while 32 Orionis is the Flamsteed designation. This system is visible to the naked eye as a faint point of light with a combined apparent visual magnitude of 4.20. It is located approximately 303 light-years away from the Sun based on parallax, and is drifting further away with a radial velocity of +18.6 km/s.

The system is a member of the eponymous 32 Orionis group, a young, nearby association of 46 co-moving stars first discovered in 2007.

The primary component of this system is a B-type main-sequence star with a stellar classification of B5V and a magnitude around 4.43. This is actually a spectroscopic binary with an orbital period of 3.964 days and eccentricity of 0.38. The unseen companion has an estimated mass of 0.6 times that of the Sun. Component B, at an angular separation of $1.08 arcsecond$ from the primary, is a class B7V star with a magnitude of 5.8, orbiting with the primary at a period of 614 years and eccentricity 0.22.
