About: 1 Scorpii

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

1 Scorpii, or b Scorpii, is a single star in the southern zodiac constellation of Scorpius. It has an apparent magnitude of 4.63, which is bright enough to be faintly visible to the naked eye on a dark night. The star shows an annual parallax shift of 6.59 mas from Earth's orbit, which equates to a distance of roughly 490 light years. It is a probable (89% chance) member of the Sco OB2 moving group.

  • 1 Scorpii (b Scorpii, b Sco, HD 141637, HIP 77635) je hvězda v souhvězdí Štíra spektrálního typu B1,5Vn. Jeho zdánlivá velikost je 4,63. Vzhledem k tomu, že se nachází 522 světelných let od Země, činí její absolutní velikost −1,39. (cs)
  • 1 Scorpii, or b Scorpii, is a single star in the southern zodiac constellation of Scorpius. It has an apparent magnitude of 4.63, which is bright enough to be faintly visible to the naked eye on a dark night. The star shows an annual parallax shift of 6.59 mas from Earth's orbit, which equates to a distance of roughly 490 light years. It is a probable (89% chance) member of the Sco OB2 moving group. This is a B-type main-sequence star with a stellar classification of B1.5 Vn, where the 'n' suffix indicates "nebulous" absorption lines being induced by rapid rotation. It has a projected rotational velocity of 310 km/s, which is giving the star an oblate shape with an equatorial bulge that is 13% wider than the polar radius. There is some weak evidence that this is a Be star with a gaseous disk that is being viewed edge-on. 1 Scorpii is a young star at around 10 million years old, with 8.3 times the mass of the Sun and 3.7 times the Sun's radius. The star is radiating 3,890 times the Sun's luminosity from its photosphere at an effective temperature of about 24,000 K. (en)

  • 1 Scorpii, som är stjärnans Flamsteed-beteckning, är en ensam stjärna, belägen i den mellersta delen av stjärnbilden Skorpionen och har även Bayer-beteckningen b Scorpii. Den har en skenbar magnitud av ca 4,63 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 6,6 mas, beräknas den befinna sig på ett avstånd på ca 490 ljusår (ca 152 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -3 km/s. Stjärnan ingår med 89 procent sannolikhet i rörelsegruppen Scorpius OB2. (sv)
