About: Chi Pegasi

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

Chi Pegasi, Latinised from χ Pegasi, is a single star in the northern constellation of Pegasus, along the eastern constellation border with Pisces. It has a reddish hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.80. The distance to this star is approximately 368 light-years based on parallax, but it is drifting closer with a radial velocity of −46 km/s. Chi Pegasi is a suspected small-amplitude variable. Koen and Eyer examined the Hipparcos data for Chi Pegasi, and found that its brightness varied by 0.0094 magnitudes, with a period of 5.9641 days.

  • Chi Pegasi, Latinised from χ Pegasi, is a single star in the northern constellation of Pegasus, along the eastern constellation border with Pisces. It has a reddish hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.80. The distance to this star is approximately 368 light-years based on parallax, but it is drifting closer with a radial velocity of −46 km/s. This is an aging red giant star on the asymptotic giant branch with a stellar classification of M2+III. It is about 8 billion years old with a mass 6% greater than the Sun's. With the supply of hydrogen at its core exhausted, the star has cooled and expanded to 53 times the girth of the Sun. It is radiating around 435 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 3,842 K. Chi Pegasi is a suspected small-amplitude variable. Koen and Eyer examined the Hipparcos data for Chi Pegasi, and found that its brightness varied by 0.0094 magnitudes, with a period of 5.9641 days. (en)
  • Chi Pegasi (χ Pegasi, förkortat Chi Peg, χ Peg) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den östra delen av stjärnbilden Pegasus. Den har en skenbar magnitud på 4,80 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 8,9 mas, beräknas den befinna sig på ett avstånd på ca 368 ljusår (ca 113 parsek) från solen. (sv)
  • Chi Pegasi (89 Pegasi) é uma estrela na direção da constelação de Pegasus. Possui uma ascensão reta de 00h 14m 36.11s e uma declinação de +20° 12′ 24.1″. Sua magnitude aparente é igual a 4.80. Considerando sua distância de 326 anos-luz em relação à Terra, sua magnitude absoluta é igual a −0.21. Pertence à classe espectral M2III. (pt)
