| dbo:abstract | Rho2 Cancri (ρ2 Cancri) is a solitary, yellow-hued star in the constellation Cancer. With an apparent visual magnitude of 5.22, it is visible to the naked eye on a dark night. Based upon an annual parallax shift of 6.70 mas as seen from Earth, this star is located around 490 light-years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.06 due to interstellar dust. At the age of about 234 million years, is an evolved, G-type giant star with a stellar classification of G8 III. It has an estimated 3.6 times the mass of the Sun and has expanded to 24 times the Sun's radius. It is radiating 310 times the Sun's luminosity from its photosphere at an effective temperature of 4,994 K.

(it) Rho2 Cancri (ρ2 Cancri, förkortad Rho2 Cnc, ρ2 Cnc), som är stjärnans Bayer-beteckning, är en ensam stjärna i norra delen av stjärnbilden Kräftan. Den har en skenbar magnitud av 5,22 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 6,7 mas, beräknas den befinna sig på ett avstånd av ca 490 ljusår (149 parsek) från solen. På det beräknade avståndet minskas dess skenbara magnitud med 0,06 enheter genom en skymningsfaktor orsakad av interstellärt stoft.

Considerando sua distância de 574 anos-luz em relação à Terra, sua magnitude absoluta é igual a −1.00. Pertence à classe espectral G8II-III.
