| dbo:abstract | Sigma2 Cancri, Latinized from σ2 Cancri, is the Bayer designation for a solitary, white-hued star in the constellation Cancer. It is faintly visible to the naked eye, with an apparent visual magnitude of +5.44. Based upon an annual parallax shift of 16.79 mas as seen from Earth, this star is located around 194 light years from the Sun. With an estimated age of 441 million years, this is an A-type subgiant star with a stellar classification of A7 IV. It is spinning relatively rapidly with a projected rotational velocity of 133 K. The star has an estimated 1.8 times the mass of the Sun and is radiating 21.5 times the Sun's luminosity from its photosphere at an effective temperature of roughly 8,309 K.

(it) Sigma2 Cancri (59 Cancri) é uma estrela na direção da constelação de Cancer. Possui uma ascensão reta de 08h 56m 56.63s e uma declinação de +32° 54′ 38.1″. Sua magnitude aparente é igual a 5.44. Considerando sua distância de 195 anos-luz em relação à Terra, sua magnitude absoluta é igual a 1.56. Pertence à classe espectral A7IV. (pt) Sigma2 Cancri (σ2 Cancri, förkortad Sigma2 Cnc, σ2 Cnc), som är stjärnans Bayer-beteckning, är en ensam stjärna i norra delen av stjärnbilden Kräftan. Den har en skenbar magnitud av 5,44 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 16,8 mas, beräknas den befinna sig på ett avstånd av ca 194 ljusår (60 parsek) från solen.
