HD 100825 is a single star in the southern constellation of Centaurus. It has the Bayer designation C2 Centauri, while HD 100825 is the identifier from the Henry Draper catalogue. The star has a yellow-white hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.26. It is located at a distance of 187 light years from the Sun based on parallax, with an absolute magnitude of +1.31. The radial velocity is poorly constrained, but the star appears to be drifting further away from the Sun at the rate of around 5 km/s. It is a member of the Sirius supercluster of co-moving stars.

  • HD 100825 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Kentauren som också har Bayer-beteckningen C2 Centauri. Den har en skenbar magnitud av ca 5,26 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 17,4 mas, beräknas den befinna sig på ett avstånd på ca 187 ljusår (ca 58 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 5 km/s. Stjärnan ingår i Sirius superhop av stjärnor med gemensam egenrörelse. (sv)

  • HD 100825 is a single star in the southern constellation of Centaurus. It has the Bayer designation C2 Centauri, while HD 100825 is the identifier from the Henry Draper catalogue. The star has a yellow-white hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.26. It is located at a distance of 187 light years from the Sun based on parallax, with an absolute magnitude of +1.31. The radial velocity is poorly constrained, but the star appears to be drifting further away from the Sun at the rate of around 5 km/s. It is a member of the Sirius supercluster of co-moving stars. This is an Am star or metallic-line star with a stellar classification of F0V, indicating it is a F-type main-sequence star that is generating energy by core hydrogen fusion. It is an estimated 467 million years old and has 1.62 times the mass of the Sun. The star is radiating 21 times the luminosity of the Sun from its photosphere at an effective temperature of 7,737 K.

  • HD 100825 (C2 Centauri) é uma estrela na constelação de Centaurus. Tem uma magnitude aparente visual de 5,25, sendo visível a olho nu em locais com pouca poluição luminosa. Com base em medições de paralaxe, está localizada a aproximadamente 188 anos-luz (57,5 parsecs) da Terra. Esta é uma estrela de classe A ou F da sequência principal que já foi classificada com um tipo espectral de F0V ou A7m, com a notação 'm' indicando que é uma estrela com linhas metálicas (estrela Am). Tem uma massa próxima de 1,6 vezes a massa solar e uma idade mais provável na faixa de 0,4 a 1,1 bilhões de anos. Seu raio foi calculado diretamente a partir de um raio angular de 0,213 milissegundos de arco, sendo equivalente a 2,66 vezes o raio solar. Está irradiando de sua fotosfera 23 vezes a luminosidade solar a uma temperatura efetiva de 7 750 K. Não possui estrelas companheiras conhecidas. (pt)
