HD 177830 [SEP] constellation
HD 177830
HD 177830 is a 7th magnitude binary star system located approximately 205 light-years away in the constellation of Lyra. The primary star is slightly more massive than our Sun, but cooler being a type K star. Therefore, it is a subgiant clearly more evolved than the Sun. In visual light it is four times brighter than the Sun, but because of its distance, about 205 light years, it is not visible to the unaided eye. With binoculars it should be easily visible.

Determination of the metallicity of HD 108063 has only been made more recently, with the first value made photometrically in 2004. Their Fe/H of 0.66 dex is slightly higher than the spectroscopic value of Fe/H = 0.55 ± 0.06 dex, 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
