14 Cancri

For other stars with this Bayer designation, see ψ Cancri.

14 Cancri is a star in the northern zodiac constellation of Cancer. It can be referred to as ψ Cancri, very occasionally as its Bayer designation of ψ² Cancri, to distinguish it from 13 Cancri, which is sometimes called ψ¹ Cancri.^[7] This star is just barely visible to the naked eye, having an apparent visual magnitude of +5.73.^[3] Based upon an annual parallax shift of 24.85 mas as seen from Earth,^[2] it is located 131 light-years (40 pc) distant. It is drifting closer to the Sun with a line of sight velocity of −44 km/s,^[4] and may be a member of the Wolf 630 moving group of stars.^[8]

This object has a stellar classification of G7 V,^[5] which presents as a G-type main-sequence star. However, it is actually a more evolved subgiant star as indicated by a surface gravity of log g = 3.87 and its position in the H-R diagram. 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]
