About: HD 74772

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

HD 74772 (d Velorum) is a single star in the southern constellation of Vela. It is positioned near the Vela SNR, which gives it an intense X-ray background. The star is of apparent visual magnitude 4.05, and hence is visible to the naked eye. Based upon an annual parallax shift of 15.8 mas, it is located 207 light years from the Sun. It is moving closer to the Earth with a heliocentric radial velocity of −2 km/s.

  • HD 74772 (d Velorum) is a single star in the southern constellation of Vela. It is positioned near the Vela SNR, which gives it an intense X-ray background. The star is of apparent visual magnitude 4.05, and hence is visible to the naked eye. Based upon an annual parallax shift of 15.8 mas, it is located 207 light years from the Sun. It is moving closer to the Earth with a heliocentric radial velocity of −2 km/s. This is an evolved G-type giant star with a stellar classification of G6 III. The interferometry-measured angular diameter of this star is 1.73±0.12 mas, which, at its estimated distance, equates to a physical radius of about 12 times the radius of the Sun. It has 3.2 times the mass of the Sun and is radiating 128 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 5,210 K. (en)

  • HD 74772 är en ensam stjärna belägen i den norra delen av stjärnbilden Seglet och som också har Bayer-beteckningen d Velorum. Den befinner sig nära Vela SNR, vilket ger en intensiv bakgrund av röntgenstrålning. Den har en skenbar magnitud av ca 4,05 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 15,8 mas, beräknas den befinna sig på ett avstånd på ca 207 ljusår (ca 63 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -2 km/s. (sv)
