34 Cancri is astar in thezodiacconstellation ofCancer, 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 anapparent visual magnitude of 6.48.[2] At the distance of this star, its visual magnitude is diminished by anextinction of 0.14 due tointerstellar dust.[8]
This is anA-type main-sequence star with astellar classification of A1 V.[3] It is achemically 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 moderateprojected rotational velocity of 18 km/s.[6] It has an estimated 2.7[6] times themass of the Sun and about 2.7[7] times the Sun's radius. The star is radiating 70[2] times theSun's luminosity from itsphotosphere at aneffective temperature of 9,661 K.[6]
