70 Cancri (original) (raw)
70 Cancri is a star in the zodiac constellation of Cancer, located around 580 light years from the Sun. It is a challenge to view with the naked eye even under good seeing conditions, having an apparent visual magnitude of 6.7. The star is moving closer to the Earth with a heliocentric radial velocity of -21 km/s, and is expected to come to within 44 light-years in around nine million years. It is an A-type main-sequence star with a stellar classification of A1V. The object has a radius of about 2.7 R☉ and is radiating 76 times the Sun's luminosity from its photosphere at an effective temperature of 8,887 K.

The star is moving closer to the Earth with a heliocentric radial velocity of -21 km/s, and is expected to come to within 44 light-years in around nine million years.

(en) 70 Cancri è una stella bianca nella sequenza principale di magnitudine 6,68 situata nella costellazione del Cancro. Dista 540 anni luce dal sistema solare. (it) 70 Cancri, som är stjärnans Flamsteed-beteckning, är en ensam stjärna, belägen i den norra delen av stjärnbilden Kräftan. Den har en skenbar magnitud av ca 6,67 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallax enligt Gaia Data Release 2 på ca 5,6 mas, beräknas den befinna sig på ett avstånd på ca 580 ljusår (ca 178 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -21 km/s och förväntas komma inom 44 ljusår från solen om ca 9 miljoner år. (sv) 70 Рака (лат. 70 Cancri) — звезда, которая находится в созвездии Рака. Это белая звезда спектрального класса А, карлик главной последовательности, удалённая на расстояние 605 световых лет и имеющая видимую звёздную величину +6.67, то есть не может быть различима невооружённым глазом, но можно её разглядеть в бинокль.
