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. [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]
