36 Cancri is a star located in the southern part of the zodiac constellation Cancer, approximately 501 light years away from the Sun. It is also known by its Bayer designation c Cancri and its Flamsteed designation 36 Cancri. This star is visible to the naked eye as a faint, white-hued object with an apparent visual magnitude of 5.92.[2] It is moving away from 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]
