About: HD 189276

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

HD 189276 is a single star in the northern constellation Cygnus, positioned near the northern constellation border with Draco. It has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.98. The star is located at a distance of approximately 820 light years from the Sun based on parallax, and it has an absolute magnitude of −2.25. It is drifting further away with a radial velocity of +4 km/s. The star has a high peculiar velocity of 38.5+1.8−2.2 km/s and thus is a probable runaway star.

  • HD 189276 is a single star in the northern constellation Cygnus, positioned near the northern constellation border with Draco. It has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.98. The star is located at a distance of approximately 820 light years from the Sun based on parallax, and it has an absolute magnitude of −2.25. It is drifting further away with a radial velocity of +4 km/s. The star has a high peculiar velocity of 38.5+1.8−2.2 km/s and thus is a probable runaway star. This is an aging star on the red giant branch with a stellar classification of K4.5IIIa. With the supply of hydrogen at its exhausted, it has cooled and expanded to 178 times the girth of the Sun. This is an active star that appears to be approaching the tip of the red-giant branch. Interferometric measurements of the star suggest significant departures from symmetry. HD 189276 has four times the mass of the Sun and is radiating 1,533 times the Sun's luminosity from its bloated photosphere at an effective temperature of 3,940. (en)
  • HD 189276 är en ensam stjärna belägen i den norra delen av stjärnbilden. Den har en skenbar magnitud av ca 4,98 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 4,0 mas, beräknas den befinna sig på ett avstånd på ca 820 ljusår (ca 251 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 4,3 km/s. Den har en relativt stor egenrörelse av 38,5+1,8 -2,2 km/s och är sålunda en tänkbar flyktstjärna. (sv)
