[12] The apparent visual magnitude of 37 Geminorum is 5.74,[2] which is just bright enough to be visible to the naked eye on a dark night.
[1] This star is drifting closer with a radial velocity of −15 km/s, and is predicted to come as near as 13.8 light-years in approximately a million years.
[5] It is positioned close enough to the ecliptic to be subject to lunar occultations, such as happened on April 8, 1984.
[13] The stellar classification of 37 Geminorum is G0 V,[3] which indicates it is an ordinary G-type main sequence star that is generating energy through core hydrogen fusion.
[6] 37 Geminorum is radiating 1.3 times the luminosity of the Sun from its photosphere at an effective temperature of 6,060 K.[1] As of 2012, no extrasolar planets or debris disks have yet been discovered around it.
