About: HD 162020

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

HD 162020 is a star in the southern constellation of Scorpius with a likely red dwarf companion. It has an apparent visual magnitude of 9.10, which is too faint to be visible to the naked eye. The distance to this system is 101 light years based on stellar parallax. It is drifting closer to the Sun with a radial velocity of −27 km/s, and is predicted to come to within ~18 light-years in 1.1 million years.

dbo:abstract
  • HD 162020 ist ein rund 30 Parsec (100 Lichtjahre) von der Erde entfernter Stern der Spektralklasse K3 mit einer scheinbaren Helligkeit von 9,1 mag. Der Stern weist etwa drei Viertel der Masse unserer Sonne auf. Der Stern wird von einem massearmen spektroskopischen Begleiter umrundet, bei dem es sich um einen Roten Zwerg oder um einen Braunen Zwerg handeln könnte. Das Objekt hat eine Mindestmasse von 14 Jupitermassen und eine Umlaufperiode von 8,4 Tagen. (de)
  • HD 162020 is a star in the southern constellation of Scorpius with a likely red dwarf companion. It has an apparent visual magnitude of 9.10, which is too faint to be visible to the naked eye. The distance to this system is 101 light years based on stellar parallax. It is drifting closer to the Sun with a radial velocity of −27 km/s, and is predicted to come to within ~18 light-years in 1.1 million years. This is an ordinary K-type main-sequence star with a stellar classification of K3V. The age estimate is poorly constrained but it appears to have an intermediate age of several billion years. However, the activity level suggests a younger star; the rotation rate of the star may have been increased through synchronization with the companion, resulting in a higher than normal activity for its age. X-ray emission has been detected from this star. HD 162020 has 74% of the mass of the Sun and 73% of the Sun's radius. The abundance of iron is roughly the same as the Sun, suggesting a similar metallicity. It is radiating just 25.8% of the luminosity of the Sun from its photosphere at an effective temperature of 4,801 K. The star is spinning with a projected rotational velocity of 1.9 km/s. (en)

  • HD 162020 é uma estrela na constelação de Scorpius. Tem uma magnitude aparente visual de 9,12, sendo invisível a olho nu. De acordo com dados de paralaxe, do terceiro lançamento do catálogo Gaia, está localizada a uma distância de 102,4 anos-luz (31,4 parsecs) da Terra. Isso corresponde a uma magnitude absoluta de 6,64. Esta estrela é uma anã laranja com um tipo espectral de K3V e uma massa de cerca de 75% da massa solar. Em 2000, foi anunciada a descoberta de uma provável anã marrom ao seu redor. (pt)
  • HD 162020 är en ensam stjärna belägen i den södra delen av stjärnbilden Skorpionen. Den har en skenbar magnitud av ca 9,10 och kräver ett mindre teleskop för att kunna observeras. Baserat på parallax enligt Gaia Data Release 2 på ca 32,4 mas, beräknas den befinna sig på ett avstånd på ca 101 ljusår (ca 31 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -27 km/s och beräknas komma inom ett avstånd av 18 ljusår om 1,1 miljoner år. (sv)
