37 Geminorum is a star located at the northwest part of the northern zodiac constellation of Gemini. Its distance from the Sun is about 56.2 light years. It is a solitary, G-type main sequence star with a stellar classification of G0 V. No extrasolar planets have yet been discovered around it.

37 Geminorum has many physical properties in common with the Sun and is one of the nearest solar analogs. Due to this fact some scientists believe that the prospects for life in its vicinity are good. In September 2003, 37 Geminorum was identified by astrobiologist Margaret Turnbull from the University of Arizona in Tucson as one of the most promising nearby candidates for hosting life, based on her analysis of the HabCat list of stars.

There was a METI message sent to 37 Geminorum. It was transmitted from Eurasia's largest radar, 70-meter Yevpatoria Planetary Radar. The message was named the Teen Age Message, it was sent on September 3, 2001, and it will arrive at 37 Geminorum in December 2057.

An exact solar twin would be a G2V star with a 5,778K temperature, be 4.6 billion years old, with the correct metallicity and a 0.1% solar luminosity variation. Stars with an age of 4.6 billion years are at the most stable state. Proper metallicity and size are also very important to low luminosity variation.
