35 Cancri is a star in the zodiac constellationofCancer, located 630 light years from the Sun. It is a challenge to view with the naked eye even under good seeing conditions, having an apparent visual magnitude of +6.55.[2] The star is moving further from the Earth with a heliocentric radial velocity of +35 km/s,[2] and is a member of the Beehive Cluster.[8]
This is a subgiant star[3] with a stellar classification of G0 III.[4] It is rotating at a relatively fast clip, giving it an oblate shape with an equatorial bulge that is 5% larger than the polar radius.[9] 35 Cancri has a projected rotational velocity of 99 km/s[5] and a rotation period of 0.5 days.[5] This rotation is expected to decrease significantly as the star expands into a giant.[4] It has nearly the same mass and size as the Sun,[5] but is radiating 77[2] times the Sun's luminosity from its photosphere at an effective temperature of 5,950 K.[6]
