About: HD 220689

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

HD 220689 is a single star in the equatorial constellation of Aquarius. It is a challenge to view with the naked eye, having an apparent visual magnitude of +7.74, but is readily viewed with a pair of binoculars. The star is located at a distance of 153 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +12 km/s. A survey in 2015 has ruled out the existence of any additional stellar companions at projected distances from 26 to 305 astronomical units.

  • HD 220689 is a single star in the equatorial constellation of Aquarius. It is a challenge to view with the naked eye, having an apparent visual magnitude of +7.74, but is readily viewed with a pair of binoculars. The star is located at a distance of 153 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +12 km/s. A survey in 2015 has ruled out the existence of any additional stellar companions at projected distances from 26 to 305 astronomical units. The stellar classification of HD 220689 is G3V, matching a yellow hued G-type main-sequence star that is generating energy through core hydrogen fusion. It is roughly 4.6 billion years old and is spinning with a projected rotational velocity of 5.5 km/s, giving it a rotation period of around 29 days. The star has a similar size, mass, and elemental abundances as the Sun. It is radiating 1.5 times the luminosity of the Sun from its photosphere at an effective temperature of 5,921 K. (en)
  • HD 220689 är en ensam stjärna belägen i den södra delen av stjärnbilden Vattumannen. Den har en skenbar magnitud av ca 7,74 och kräver åtminstone en stark handkikare för att kunna observeras. Baserat på parallax enligt Gaia Data Release 2 på ca 21,3 mas, beräknas den befinna sig på ett avstånd på ca 153 ljusår (ca 47 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 12 km/s. (sv)
