8 Cancri is a single,[7] white-hued star in the zodiac constellation of Cancer. It has an apparent visual magnitude of +5.14,[2] which indicates it is faintly visible to the naked eye under suitable viewing conditions. The distance to this star, as determined from its annual parallax shift of 15.20 mas,[1] is around 215 light years. A radial velocity of +21 km/s indicates it is moving away from the Sun.[4]
This is an A-type main-sequence star with a stellar classification of A1 V.[3] It is a young star with an estimated age of just 144[5] million years, and has a high rate of spin with a projected rotational velocity of 173 km/s.[5] 8 Cancri has 2.37[5] times the mass of the Sun and is radiating 36.6[2] times the Sun's luminosity from its photosphere at an effective temperature of around 10,352 K.[5]
