82 Cancri is a solitary,[1] 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.[2] 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 540 light years from the Sun based on parallax. At that range, the visual magnitude is diminished by an extinction of 0.10 magnitudes due to interstellar dust.[4] It is drifting further away with a radial velocity of +27 km/s.[5]

This is an evolved K-type giant star with a stellar classification of K1 III,[1] having exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence. The star currently has 31[6] times the girth of the Sun and is spinning slowly with a projected rotational velocity. It is radiating over 300 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,340 K.[6] Based on its abundance of iron, the star has a lower abundances of heavier elements than the Sun.[7]
