54 Cancri is a star in the zodiac constellation of Cancer. It has an apparent visual magnitude of 6.38, which places it just below the normal brightness limit of stars visible to the naked eye. The annual parallax shift is 24.79 mas as measured from Earth's orbit, which yields a distance estimate of about 132 light years. It is moving away from the Sun with a radial velocity of +45 km/s.

  • 54 Cancri è una stella nana gialla nella sequenza principale di magnitudine 6,38 situata nella costellazione del Cancro. Dista 130 anni luce dal sistema solare. (it)
  • 54 Cancri, som är stjärnans Flamsteed-beteckning, är en ensam stjärna, belägen i den mellersta delen av stjärnbilden Kräftan. Den har en skenbar magnitud av ca 6,38 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallax enligt Gaia Data Release 2 på ca 24,8 mas, beräknas den befinna sig på ett avstånd på ca 132 ljusår (ca 40 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 45 km/s. (sv)
  • 54 Рака (лат. 54 Cancri) — звезда, которая находится в созвездии Рака.

Находится от Земли на расстоянии 130 световых лет и имеет видимую звёздную величину +6.36, то есть звезда невидима невооружённым глазом, но её можно разглядеть в бинокль. (ru)

  • 54 Cancri is a star in the zodiac constellation of Cancer. It has an apparent visual magnitude of 6.38, which places it just below the normal brightness limit of stars visible to the naked eye. The annual parallax shift is 24.79 mas as measured from Earth's orbit, which yields a distance estimate of about 132 light years. It is moving away from the Sun with a radial velocity of +45 km/s. Measurement of the stars proper motion over time suggest changes due to an acceleration component, which may indicate it is a close binary system. The visible component has a stellar classification of G5 V, indicating it is an ordinary G-type main-sequence star that is generating energy through hydrogen fusion in its core region. Hall et al. (2007) classify it as a low-activity variable star. The star is about five billion years old with a projected rotational velocity of 3.1 km/s. It has 1.23 times the mass of the Sun and 1.81 times the Sun's radius. (en)
