| dbo:abstract | 50 Cancri is a single star in the zodiac constellation of Cancer, located 183 light years away from the Sun. It has the Bayer designation A2 Cancri; 50 Cancri is the Flamsteed designation. It is faintly visible to the naked eye as a white-hued star with an apparent visual magnitude of 5.89. The star is moving away from the Earth with a heliocentric radial velocity of 23 km/s, having come to within 118 light-years some 1.2 million years ago. This is a chemically peculiar A-type main-sequence star with a stellar classification of A1 Vp. It is a Lambda Boötis star displaying strongly-depleted iron peak and alpha process elements, but otherwise relatively normal solar abundances. The star shows no variability down to a detection limit of 1.6 millimagnitudes. It is 264 million years old with a relatively low projected rotational velocity of 18 km/s. 50 Cancri has 2.1 times the mass of the Sun and is radiating 11 times the Sun's luminosity from its photosphere at an effective temperature of 8,340 K. 50 Cancri has an infrared excess, which most likely indicates a debris disk in orbit around the host star. A blackbody model of the emission shows a two component fit, with the warm section having a temperature of 246±91 K at a radius of 4±3 AU from the star, and a cool component at 108±21 K with a separation of 22±8 AU.

(it) 50 Cancri (A² Cancri) é uma estrela na direção da Cancer. Possui uma ascensão reta de 08h 46m 56.06s e uma declinação de +12° 06′ 36.3″. Sua magnitude aparente é igual a 5.89. Considerando sua distância de 199 anos-luz em relação à Terra, sua magnitude absoluta é igual a 1.96. Pertence à classe espectral A1V. (pt) 50 Cancri, som är stjärnans Flamsteed-beteckning, är en ensam stjärna, belägen i den södra delen av stjärnbilden Kräftan och har även Bayer-beteckningen A2 Cancri. Den har en skenbar magnitud av ca 5,89 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 17,8 mas, beräknas den befinna sig på ett avstånd på ca 183 ljusår (ca 56 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 23 km/s. (sv) 50 Рака (лат. 50 Cancri) — звезда в созвездии Рака.

Это карлик белого цвета спектрального класса А главной последовательности. (ru) |
