About: HD 240210

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

HD 240210 is a star in the northern constellation of Cassiopeia. It has an orange hue but is too faint to be viewed with the naked eye, having an apparent visual magnitude of 8.33. Parallax measurements provide an estimate of its distance from the Sun as approximately 1,230 light years. It is drifting further away with a radial velocity of +8.6 km/s. On June 10, 2009 a planet orbiting the star was discovered by Niedzielski et al. This exoplanet is a 6.9 or greater Jupiter mass planet. Evidence for additional planetary companions has been found.

dbo:abstract
  • HD 240210 is a star in the northern constellation of Cassiopeia. It has an orange hue but is too faint to be viewed with the naked eye, having an apparent visual magnitude of 8.33. Parallax measurements provide an estimate of its distance from the Sun as approximately 1,230 light years. It is drifting further away with a radial velocity of +8.6 km/s. This is an aging giant star with a class of K3, which has exhausted the supply of hydrogen at its core and expanded to 25 times the radius of the Sun. It is around three billion years old with 1.3 times the Sun's mass. The star is radiating 152 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,019 K. It is spinning slowly, with each rotation taking at least 1.8 years. On June 10, 2009 a planet orbiting the star was discovered by Niedzielski et al. This exoplanet is a 6.9 or greater Jupiter mass planet. Evidence for additional planetary companions has been found. (en)
  • HD 240210は、カシオペヤ座の方角におよそ466光年の距離にある恒星である。 (ja)
  • HD 240210 är en ensam stjärna, belägen i den mellersta delen av stjärnbilden Cassiopeja. Den har en skenbar magnitud av ca 8,33 och kräver åtminstone en stark handkikare eller ett mindre teleskop för att kunna observeras. Baserat på parallax enligt Gaia Data Release 2 på ca 2,7 mas, beräknas den befinna sig på ett avstånd på ca 1 230 ljusår (ca 376 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 8,6 km/s. (sv)
