السرطان 5 بالإنكليزية (كانكري 5 - 5 Cancri) هو نجم في كوكبة السرطان. حجمه الظاهر هو 5،99. (ar) 5 Cancri is a single star in the zodiac constellation of Cancer, located around 520 light years away from the Sun. It is just visible to the naked eye under good seeing conditions as a dim, blue-white hued star with an apparent visual magnitude of 5.99. This object is moving closer to the Sun with a heliocentric radial velocity of −10 km/s. At one point this was thought to be a spectroscopic binary system. It is a Be star with a weak circumstellar disk of gas that has around three times the radius of the host star. The stellar classification of 5 Cancri is B9.5 Vn, matching a B-type main-sequence star with "nebulous" lines due to rapid rotation. It is 36 million years old with a high projected rotational velocity of 188 km/s. The star has 2.9 times the mass of the Sun and about 3.1 times the Sun's radius. It is radiating 121 times the Sun's luminosity from its photosphere at an effective temperature of 9,727 K. (en) 5 Cancri è una stella bianco-azzurra nella sequenza principale di magnitudine 5,98 situata nella costellazione del Cancro. Dista 472 anni luce dal sistema solare. (it) 5 Cancri, som är stjärnans Flamsteed-beteckning, är en ensam stjärna, belägen i den östra delen av stjärnbilden Kräftan. Den har en skenbar magnitud som varierar 5,99 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 6,2 mas, beräknas den befinna sig på ett avstånd på ca 520 ljusår (ca 161 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -10 km/s. (sv) |
