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.[1] It is located at a distance of 187 light years from the Sun based on parallax, with an absolute magnitude of +1.31.[1] 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.[1] 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[2] from its photosphere at an effective temperature of 7,737 K.[5]
