About: 56 Orionis

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

56 Orionis is a single, variable star in the equatorial constellation of Orion. It has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude that fluctuates around 4.76. The star is located at a distance of approximately 1,130 light years from the Sun based on parallax. It is drifting further away with a radial velocity of +11 km/s. The star has a peculiar velocity of 19.0+2.9−3.1 km/s relative to its neighbors, and may be a runaway star. It has one reported visual companion, designated component B, with magnitude 13.5 and angular separation 42.9″.

  • 56 Orionis is a single, variable star in the equatorial constellation of Orion. It has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude that fluctuates around 4.76. The star is located at a distance of approximately 1,130 light years from the Sun based on parallax. It is drifting further away with a radial velocity of +11 km/s. The star has a peculiar velocity of 19.0+2.9−3.1 km/s relative to its neighbors, and may be a runaway star. This object is a bright giant star with a stellar classification of K2-IIb. It is a suspected variable star of unknown type with a brightness that has been measured varying from 4.73 down to 4.78. The star is about 61 million years old with 6.4 times the mass of the Sun and is spinning with a projected rotational velocity of 3.5. Having exhausted the supply of hydrogen at its core, the star has expanded to 92 times the radius of the Sun. It is radiating 2,547 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,270 K. It has one reported visual companion, designated component B, with magnitude 13.5 and angular separation 42.9″. (en)

  • 56 Orionis, som är stjärnans Flamsteed-beteckning är en ensam stjärna i den mellersta delen av stjärnbilden Orion. Den har en genomsnittlig skenbar magnitud på ca 4,76 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 2,9 mas, beräknas den befinna sig på ett avstånd på ca 1 130 ljusår (ca 350 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet av ca 11 km/s. Stjärnan har en egenrörelse på 19,0+2,9−3,1 km/s i förhållande till dess grannar, och kan vara en flyktstjärna. (sv)
