37 Cancri is a star in the zodiac constellation of Cancer. It is a challenge to view with the naked eye, having an apparent magnitude of 6.54.[2] The star is moving away from the Earth with a heliocentric radial velocity of +22 km/s, having come as close as Script error: No such module "convert". some 2.7 million years ago.[6]

This is an ordinary A-type main-sequence star with a stellar classification of A1 V,[4] which indicates it is generating energy through hydrogen fusion at its core. It is spinning with a projected rotational velocity of 35 km/s.[2] The star has 2.7[3] times the mass of the Sun and around 1.8[7] times the Sun's radius. It is radiating 31 times the luminosity of the Sun from its photosphere at an effective temperature of 9,830 K.[2]
