About: 28 Monocerotis

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

28 Monocerotis is a single star in the equatorial constellation of Monoceros. It has an orange-hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.69. The distance to this star is approximately 450 light years based on parallax, and it has an absolute magnitude of −1.00. The star is drifting further away from the Sun with a radial velocity of +26.7 km/s. Measurement of the star's proper motion anomaly by the Gaia spacecraft suggests a companion may be orbiting the star at a distance of 1.9 AU.

  • 28 Monocerotis is a single star in the equatorial constellation of Monoceros. It has an orange-hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.69. The distance to this star is approximately 450 light years based on parallax, and it has an absolute magnitude of −1.00. The star is drifting further away from the Sun with a radial velocity of +26.7 km/s. This is an aging giant star with a stellar classification of K4III, having exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence. The spectrum of the star shows abnormally strong lines of CN. It is classified as an FK Comae Berenices variable, varying by 0.02 magnitude over a period of 0.21 days. FK Comae Berenices variables are typically rapidly-rotating stars, but the measured projected rotational velocity of 28 Monocerotis is low. The star has expanded to 48 times the radius of the Sun. It is radiating 524 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 3,999 K. Measurement of the star's proper motion anomaly by the Gaia spacecraft suggests a companion may be orbiting the star at a distance of 1.9 AU. (en)

  • 28 Monocerotis, som är stjärnans Flamsteed-beteckning, är en ensam stjärna belägen i den mellersta delen av stjärnbilden Enhörningen, som också har variabelbeteckningen V645 Monocerotis. Den har en genomsnittlig skenbar magnitud på ca 4,69 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 7,3 mas, beräknas den befinna sig på ett avstånd på ca 450 ljusår (ca 138 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet av ca 27 km/s. (sv)
