About: Zeta Hydri

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Zeta Hydri, Latinized from ζ Hydri, is a single, white-hued star in the southern constellation of Hydrus. It is faintly visible to the naked eye with an apparent magnitude of 4.83. This distance to this star can be estimated from its annual parallax shift of 11.47 mas, showing it to be about 284 light years away. It is moving further away from the Sun with a radial velocity of +3.6 km/s.

  • Zeta Hydri, Latinized from ζ Hydri, is a single, white-hued star in the southern constellation of Hydrus. It is faintly visible to the naked eye with an apparent magnitude of 4.83. This distance to this star can be estimated from its annual parallax shift of 11.47 mas, showing it to be about 284 light years away. It is moving further away from the Sun with a radial velocity of +3.6 km/s. The spectrum of this star matches a stellar classification of A2 IV, suggesting it is a subgiant star that is in the process of evolving away from the main sequence as the supply of hydrogen at its core becomes exhausted. It has a high rate of spin, showing a projected rotational velocity of 116 km/s. This is giving the star a slight oblate shape with an equatorial bulge that is 5% larger than the polar radius. It has 2.4 times the mass of the Sun and nearly four times the Sun's radius. Zeta Hydri is radiating 80 times the Sun's luminosity into space from its photosphere at an effective temperature of 9,144 K. (en)
  • Zeta Hydri (47 Hydri) é uma estrela na direção da constelação de Hydrus. Possui uma ascensão reta de 02h 45m 32.53s e uma declinação de −67° 37′ 00.2″. Sua magnitude aparente é igual a 4.83. Considerando sua distância de 295 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.05. Pertence à classe espectral A2IV/V. (pt)
  • Zeta Hydri (ζ Hydri, förkortat Zeta Hyi, ζ Hyi) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den mellersta delen av stjärnbilden Lilla vattenormen. Den har en skenbar magnitud på 4,83 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 11,5 mas, beräknas den befinna sig på ett avstånd på ca 284 ljusår (ca 87 parsek) från solen. (sv)
