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. This star is just barely visible to the naked eye, having an apparent visual magnitude of +5.73. Based upon an annual parallax shift of 24.85 mas as seen from Earth, it is located 131 ly pc out on distant. It is drifting closer to the Sun with a line of sight velocity of −44 km/s, and may be a member of the Wolf 630 moving group of stars. This object has a stellar classification of G7 V, 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. References 681096777089578112 cs2 . 40023 cs2 .
