29 Cancri is a star in the zodiac constellation of Cancer, located 370 light years from the Sun. It is just visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 5.94.[2] The star is situated near the ecliptic, which means it is subject to lunar occultations.[8]

This is an A-type main-sequence star with a stellar classification of A5 V,[3] which indicates it is generating energy through hydrogen fusion at its core. It has 2.3[5] times the mass of the Sun and around 1.9[6] times the Sun's radius. The star has a relatively high rate of rotation, showing a projected rotational velocity of 117 km/s.[5] It is radiating 45[5] times the Sun's luminosity from its photosphere at an effective temperature of 7,727 K.[5]
