HD 175740, BD+41°3177B and BD+41° 3177C are two components of a binary star system in the constellation Lyra, approximately 270 light years away from Earth. The main star, 5th magnitude HD 175740, is a yellow giant star of the spectral type G8III. It therefore has a surface temperature of 5,000 to 6,000 kelvins, in the same range as that of our Sun, though it is much larger and brighter in comparison. BD+41°3177B is a 13th magnitude star of an unknown spectral type.
