37 Geminorum is a solitary Sun-like star located at the northwest part of the northern constellation of Gemini, about three degrees to the east of the bright star Epsilon Geminorum. The apparent visual magnitude of 37 Geminorum is 5.74, which is just bright enough to be visible to the naked eye on a dark night. It is located at a distance of 57 light years from the Sun based on parallax. 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. It is positioned close enough to the ecliptic to be subject to lunar occultations, such as happened on April 8, 1984.




Properties


The stellar classification of 37 Geminorum is G0 V, which indicates it is an ordinary G-type main sequence star that is generating energy through core hydrogen fusion. In 2007, J. C. Hall and associates categorized it as a solar-type with a high mean activity level. The star is around 5.5 billion years old and is spinning with a rotation period of 25 days. It is slightly larger and more massive than the Sun, with a lower abundance of heavier elements based on its abundance of iron. 37 Geminorum is radiating 1.3 times the luminosity of the Sun from its photosphere at an effective temperature of 6,060 K.
As of 2012, no extrasolar planets or debris disks have yet been discovered around it. The center of the star's habitable zone lies at a distance of 1.32 AU.
