| dbo:abstract | Tau Cancri (τ Cancri) is a solitary, yellow-hued star in the zodiac constellation of Cancer. With an apparent visual magnitude of +5.42, it is faintly visible to the naked eye. Based upon an annual parallax shift of 11.92 mas as seen from Earth, it is located around 274 light-years from the Sun. With an age of about 620 million years and a stellar classification of G8 III, this is a red-clump giant star, which indicates that it has evolved onto the horizontal branch and is generating energy through helium fusion at its core. It is a microvariable, showing a luminosity variation of 0.04 in magnitude. Tau Cancri has an estimated 2.4 times the mass of the Sun and 7.8 times the Sun's radius. The star radiates 40 times the solar luminosity from its photosphere at an effective temperature of 5,153 K.

(it) Tau Cancri (τ Cancri, förkortad Tau Cnc, τ Cnc), som är stjärnans Bayer-beteckning, är en ensam stjärna i norra delen av stjärnbilden Kräftan. Den har en skenbar magnitud av 5,42 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 11,9 mas, beräknas den befinna sig på ett avstånd av ca 274 ljusår (84 parsek) från solen.
