HD 100825 is a single [7] 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. [2] It is located at a distance of 187 light years from the Sun based on parallax, with an absolute magnitude of +1.31. [2] 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. [2] It is a member of the Sirius supercluster of co-moving stars. [8]
This is an Am star [4] or metallic-line star with a stellar classification of F0V, [3] indicating it is a F-type main-sequence star that is generating energy by core hydrogen fusion. It is an estimated 467 [5] million years old and has 1.62 [5] times the mass of the Sun. The star is radiating 21 times the luminosity of the Sun [1] from its photosphere at an effective temperature of 7,737 K. [5]
