Characteristics

It is an evolved

milliarcseconds.[7] At the estimated distance by Gaia EDR3, it yields a physical size of 4.696 R☉. The star has a mass of 5.644 M☉[6] and rotates under its own axis at a speed of 25 km/s.[9]

HD 37320 is located within the constellation Orion, based on its

Gaia EDR3.[2] The apparent magnitude of the star, i.e. its brightness as seen from Earth, is of 5.852m,[1] which is above the limiting magnitude for naked-eye vision, generally defined as 6.5m, making it faintly visible to the naked eye.[3] The absolute magnitude of HD 37320, i.e. its brightness if it was seen at 10 parsecs (32.6 ly), is -1.43.[5] It is moving away from Earth at a velocity of 20.1 km/s.[4]

HD 37320 is the

Bonner Durchmusterung catalogue.[1]
