| dbo:abstract | 12 Cancri is a star in the zodiac constellation Cancer. It has an apparent visual magnitude of 6.25, placing just below the normal limit for stars visible to the naked eye in good seeing conditions. The star displays an annual parallax shift of 12.7 mas as seen from Earth's orbit, which places it at a distance of about 257 light-years. It is moving toward the Sun with a radial velocity of around −10 km/s. This is an ordinary F-type main-sequence star with a stellar classification of F3 V, which indicates it is generating energy through hydrogen fusion at its core. It is spinning with a projected rotational velocity of 52 km/s and appears to be undergoing solar-like differential rotation with relative rate of α = 0.33±0.13. The star is about 2.5 billion years old with 1.16 times the mass of the Sun and is radiating nearly 18 times the Sun's luminosity from its photosphere at an effective temperature of around 6,357 K.

(it) 12 Cancri, som är stjärnans Flamsteed-beteckning, är en ensam stjärna, belägen i den östra delen av stjärnbilden Kräftan. Den har en skenbar magnitud av 6,25 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallax-mätning inom Hipparcos-uppdraget på ca 12,5 mas, beräknas den befinna sig på ett avstånd på ca 261 ljusår (ca 80 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -10 km/s. (sv) 12 Рака (лат. 12 Cancri) — звезда, которая находится в созвездии Рака. Это жёлто-белая звезда спектрального класса F, карлик главной последовательности. (ru) |
