About: Sigma Piscium

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

Sigma Piscium (Sigma Psc, σ Piscium, σ Psc) is a main-sequence star in the zodiac constellation of Pisces. It has an apparent magnitude of +5.50, meaning it is barely visible to the naked eye, according to the Bortle scale. While parallax measurements by the Hipparcos spacecraft give a distance of approximately 430 light years (133 parsecs), dynamical parallax measurements put it slightly closer, at 368 light-years (113 parsecs) from Earth. Sigma Piscium was a latter designation of 40 Andromedae.

  • Sigma Piscium (Sigma Psc, σ Piscium, σ Psc) is a main-sequence star in the zodiac constellation of Pisces. It has an apparent magnitude of +5.50, meaning it is barely visible to the naked eye, according to the Bortle scale. While parallax measurements by the Hipparcos spacecraft give a distance of approximately 430 light years (133 parsecs), dynamical parallax measurements put it slightly closer, at 368 light-years (113 parsecs) from Earth. Sigma Piscium is a spectroscopic binary system, meaning the components of the system have been detected from periodic Doppler shifts in their spectra. In this case, light from both stars can be detected and it is double-lined. It has an orbital period of 81 days, and the orbit is relatively eccentric, at about 0.9. Both components are B-type main-sequence stars. Sigma Piscium is moving through the Milky Way at a speed of 23.5 km/s relative to the Sun. Its projected galactic orbit carries it between 24,300 and 29,400 light years from the center of the galaxy. Sigma Piscium was a latter designation of 40 Andromedae. (en)
  • Sigma Piscium (69 Piscium) é uma estrela na direção da constelação de Pisces. Possui uma ascensão reta de 01h 02m 49.09s e uma declinação de +31° 48′ 15.6″. Sua magnitude aparente é igual a 5.50. Considerando sua distância de 414 anos-luz em relação à Terra, sua magnitude absoluta é igual a −0.02. Pertence à classe espectral B9.5V. (pt)
  • Sigma Piscium (σ Piscium, förkortat Sigma Psc, σ Psc), som är stjärnans Bayerbeteckning, är en dvärgstjärna belägen i norra delen av stjärnbilden Fiskarna. Den har en skenbar magnitud på 5,50 och är svagt synlig för blotta ögat där ljusföreoreningar inte förekommer. Baserat på dynamiska parallaxmätningar beräknas att den befinner sig på ett avstånd av ca 368 ljusår (ca 113 parsek) från solen. Sigma Piscium hade tidigare beteckningen 40 Andromedae. (sv)
