About: HD 25171

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

HD 25171 is a star in the southern constellation of Reticulum, the reticle. With an apparent visual magnitude of 7.79, this star is too faint to be viewed with the naked eye. However, it is readily visible through a small telescope from the southern hemisphere. Parallax measurements made during the Hipparcos mission place it at a distance of roughly 179 light-years (55 parsecs) from Earth. It has a planetary companion that was announced December 2009. The survey in 2015 have ruled out the existence of any stellar companions at projected distances above 26 astronomical units.

  • HD 25171 is a star in the southern constellation of Reticulum, the reticle. With an apparent visual magnitude of 7.79, this star is too faint to be viewed with the naked eye. However, it is readily visible through a small telescope from the southern hemisphere. Parallax measurements made during the Hipparcos mission place it at a distance of roughly 179 light-years (55 parsecs) from Earth. It has a planetary companion that was announced December 2009. Based upon its spectrum, this is an ordinary F-type main sequence star with a stellar classification of F8 V. It is slightly larger than the Sun, with 9% more mass and an 7% greater radius. As such, it is radiating 189% of the Sun's luminosity from its outer atmosphere at an effective temperature of 6,063 K. This gives it the yellow-white hued glow of an F-type star. It appears to be roughly the same age as the Sun; around four billion years. The survey in 2015 have ruled out the existence of any stellar companions at projected distances above 26 astronomical units. (en)
  • HD 25171 — звезда в созвездии Сетки на расстоянии около 179 световых лет от нас. Вокруг звезды обращается, как минимум, одна планета. (ru)
  • HD 25171 é uma estrela binária na constelação de Reticulum. Com uma magnitude aparente de 7,79, é muito fraca para ser vista a olho nu, mas pode ser vista facilmente com um telescópio pequeno. Medições de paralaxe pela sonda Gaia mostram que está a uma distância de aproximadamente 182 anos-luz (56 parsecs) da Terra. Esta é uma estrela de classe F da sequência principal com um tipo espectral de F8V, sendo similar ao Sol porém um pouco maior e mais brilhante. A sonda Gaia descobriu que HD 25171 é um sistema binário, possuindo uma companheira anã vermelha distante. Em 2010, foi descoberto um planeta extrassolar análogo a Júpiter orbitando HD 25171. (pt)
  • HD 25171 är en ensam stjärna belägen i den södra delen av stjärnbilden Rombiska nätet. Den har en skenbar magnitud av ca 7,79 och kräver en stark handkikare eller ett mindre teleskop för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 18,2 mas, beräknas den befinna sig på ett avstånd på ca 179 ljusår (ca 55 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 43 km/s. (sv)
