HD 108063 is a somewhat bright star that lies in an area of the southern sky towards the middle of Centaurus. It has not been studied particularly extensively, but was identified as modestly high proper motion star during the previous century. With a Gaia Data Release 3 parallax of 19.0  mas , it lies at a distance of 52.4 parsecs, so the star is relatively nearby. It has been classified as a G5III [4] or G4IV star, [10] and evolutionary models place it on the subgiant branch. [2]

HD 108063 has a high metallicity, with [Fe/H] being about 0.55 dex, [11] which corresponds to a metallicity of 3.54 times the solar value. This is one of the highest metallicities for any known star, and is identical to 1σ to the Fe/H of HD 126614 (0.56±0.04 dex) and HD 177830 (0.55±0.03 dex).[ citation needed ]
