34 Cancri is a star in the zodiac constellation of Cancer, located about 568 light years away from the Sun.[1] It is a challenge to view with the naked even under good viewing conditions, having an apparent visual magnitude of 6.48.[2] At the distance of this star, its visual magnitude is diminished by an extinction of 0.14 due to interstellar dust.[8]
This is an A-type main-sequence star with a stellar classification of A1 V.[3] It is a chemically peculiar star, possibly of the magnetic-type (CP2), showing an abnormal abundance of strontium.[9] The star is an estimated 336[2] million years old with only a moderate projected rotational velocity of 18 km/s.[6] It has an estimated 2.7[6] times the mass of the Sun and about 2.7[7] times the Sun's radius. The star is radiating 70[2] times the Sun's luminosity from its photosphere at an effective temperature of 9,661 K.[6]
