36 Cancri is a star in the southern part of the zodiac constellation of Cancer, located around 501 light years away from the Sun. It has the Bayer designation c Cancri; 36 Cancri is the Flamsteed designation. This object is a visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 5.92.[2] It is moving further from the Earth with a heliocentric radial velocity of +16 km/s.[6]
This is an ordinary A-type main-sequence star with a stellar classification of A3 V,[4] which indicates it is generating energy through hydrogen fusion at its core. It has a projected rotational velocity of 44 km/s, with 2.66[3] times the mass of the Sun and double the Sun's radius.[7] The star is radiating 93[3] times the Sun's luminosity from its photosphere at an effective temperature of 8,472 K.[3]
