57 Cancri (original) (raw)
57 Cancri is a double star in the zodiac constellation of Cancer, located around 460 light years away from the Sun. They are visible to the naked eye as a faint star with a combined apparent visual magnitude of +5.40. The brighter member, designated component A. is a yellow-hued giant star with a stellar classification of G7 III and an apparent magnitude of +6.09. Its companion, component B, is an orange-hued giant with a class of K0 III and an apparent magnitude of +6.37. As of 2017, the pair had an angular separation of 1.50″ along a position angle of 310°.

The brighter member, designated component A. is a yellow-hued giant star with a stellar classification of G7 III and an apparent magnitude of +6.09.

(en) 57 Cancri è una stella binaria di magnitudine 5,42 situata nella costellazione del Cancro. Dista 365 anni luce dal sistema solare. (it) 57 Cancri, som är stjärnans Flamsteed-beteckning, är en dubbelstjärna, belägen i den norra delen av stjärnbilden Kräftan. Den har en kombinerad skenbar magnitud av ca 5,40 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 7,1 mas, beräknas den befinna sig på ett avstånd på ca 460 ljusår (ca 140 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -59 km/s.
