HD 207832 is a G-type main-sequence star. Its surface temperature is 5764±15 K. HD 207832 is slightly enriched compared to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.17±0.01 and is much younger at an age of 0.74±0.62 billion years. Kinematically, it belongs to the thin disk of the Milky Way.
A multiplicity study in 2014 detected a candidate comoving stellar companion - a red dwarf star or brown dwarf with a spectral class M6.5, at a very wide projected separation of 38.57′ (2.0 light years)
