| dbo:abstract | 82 Cancri is a solitary, 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. With an apparent visual magnitude of +5.33, 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. It is drifting further away with a radial velocity of +27 km/s. This is an evolved K-type giant star with a stellar classification of K1 III, having exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence. The star currently has 31 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. Based on its abundance of iron, the star has a lower abundances of heavier elements than the Sun.

(it) Pi2 Cancri (82 Cancri) é uma estrela na direção da constelação de Cancer. Possui uma ascensão reta de 09h 15m 13.88s e uma declinação de +14° 56′ 29.5″. Sua magnitude aparente é igual a 5.36. Considerando sua distância de 701 anos-luz em relação à Terra, sua magnitude absoluta é igual a −1.30. Pertence à classe espectral K1III. (pt) Pi2 Cancri (π2 Cancri, förkortad Pi2 Cnc, π2 Cnc), som är stjärnans Bayer-beteckning (även kallad 82 Cancri), är en ensam stjärna i östra delen av stjärnbilden Kräftan. Den har en skenbar magnitud av 5,33 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 5,4 mas, beräknas den befinna sig på ett avstånd av ca 610 ljusår (190 parsek) från solen. På det beräknade avståndet minskas dess skenbara magnitud med 0,10 enheter genom en skymningsfaktor orsakad av interstellärt stoft. (sv) |
