HD 37605 is a star in the equatorial constellation of Orion. It is orange in hue but is too faint to be visible to the naked eye, having an apparent visual magnitude of 8.67.[2] Parallax measurements yield a distance estimate of 152 light years from the Sun. It has a high proper motion[3] and is drifting closer with a radial velocity of −22 km/s.[1]
This object is a K-type main-sequence star with a stellar classification of K0 V.[3] It is an inactive, metal-rich star. Age estimates range from 1.8[4] up to 7[3] billion years old, and it is spinning with a projected rotational velocity of 4.5 km/s.[6] The star has 98% of the mass of the Sun and 89% of the Sun's radius. It is radiating 60% of the luminosity of the Sun from its photosphere at an effective temperature of 5,380 K.[4]
