14 Cancri is a star in the northern zodiac constellation of Cancer. It can be referred to as ψ Cancri, very occasionally as ψ2 Cancri, to distinguish it from 13 Cancri which is sometimes called ψ1 Cancri.[7] It is just barely visible to the naked eye, having an apparent visual magnitude of +5.73.[2] Based upon an annual parallax shift of 24.18 mas as seen from Earth,[1] it is located 135 light years from the Sun. It may be a member of the Wolf 630 moving group of stars.[8]

This object has a stellar classification of G7 V,[3] which would suggest it is a G-type main-sequence star. However, Jofré et al. (2015) consider it to be a more evolved subgiant star due to a surface gravity of log g = 3.87. As such, it has an estimated 1.5 times the mass of the Sun and 3.2 times the Sun's radius. The star is 2.4 billion years old with what appears to be a leisurely rotation rate, judging by a projected rotational velocity of 0.98 km/s. It is radiating eight times the Sun's luminosity from its photosphere at an effective temperature of 5,311 K.[4]
