HR 511 (also designated V987 Cassiopeiae and Gliese 75 among others) is an orange dwarf of spectral type K0V in the constellation Cassiopeia. With an apparent magnitude of 5.63,[3] it is faintly visible to the naked eye. The star is relatively close, 32.8 light-years from the Sun.[2]

This star is estimated to be about the same age as the Sun, with 83% of the mass of the Sun and 82% of the Sun's radius. It has not been identified as a member of any moving star groups. This star has displayed unusual emissions of Ca II and is much more x-ray luminous than the Sun. It is considered a relatively active star.[10] Based on an iron abundance of [Fe/H] = −0.02, the metallicity of this star appears to be similar to that of the Sun.[9]
