}}{{Starbox end}}35 Cancri is a star in the zodiac constellation of Cancer, 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.[3] The star is moving further from the Earth with a heliocentric radial velocity of +35 km/s,[3] and is a member of the Beehive Cluster.[21]This is a subgiant star[4] with a stellar classification of G0 III.[5] 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.[24] 35 Cancri has a projected rotational velocity of 99 km/s[12] and a rotation period of 0.5 days.[12] This rotation is expected to decrease significantly as the star expands into a giant.[5] It has nearly the same mass and size as the Sun,[12] but is radiating 77[3] times the Sun's luminosity from its photosphere at an effective temperature of 5,950 K.[15] References1. ^1 2 3 4 5 {{Cite Gaia DR2|662794169095142912}}
