82 Cancri is a solitary,[4] orange-hued star in the zodiac constellation of Cancer. It has the Bayer designation Pi2 Cancri, which is Latinized from π2 Cancri; 82 Cancri is the star's Flamsteed designation. The star lies just a degree to the south of the ecliptic.[10] With an apparent visual magnitude of +5.33,[3] it is dimly visible to the naked eye on a dark night. This star is located at a distance of approximately Script error: No such module "convert". from the Sun based on parallax measurements. At that range, the visual magnitude is diminished by an extinction of 0.10 magnitudes due to interstellar dust.[11] It is drifting further away with a radial velocity of +27.5 km/s.[5]

This is an evolved K-type giant star with a stellar classification of K1 III,[4] having exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence. The star 2.6[6] times the Sun's mass and has expanded to 31[2] times the girth of the Sun. It is spinning slowly with a projected rotational velocity. This star is radiating 435 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,703 K.[2] Based on its abundance of iron, the star has a lower abundances of heavier elements than the Sun.[7]
