HD 176051
HD 176051 is a spectroscopic binary star system〔 approximately 49 light years away from Earth in the constellation Lyra. The pair orbit with a period of 22,423 days (61.4 years) and an eccentricity of 0.25. Compared to the Sun, they have a somewhat lower proportion of elements more massive than helium.〔 Their individual masses are estimated at 1.07 and 0.71 solar masses ().〔
==Planetary system==
A planet orbiting one of the stars was discovered through astrometric observations. However, it is not known which stellar component the planet is orbiting around.
The parent star is a binary star. The planet parameters are given for the component B (Muterspaugh et al. 2010).
If the planet is orbiting the component A, its mass is 2.26 and a = 2.02 AU.
