HD 176051

Extrasolar Planets Encyclopaedia data

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. The system is moving closer to the Sun with a radial velocity of −47 km/s and will reach perihelion in about 269,000 years when it comes within roughly 5.1 pc of the Sun.

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 planet parameters are given here for the component B. But, if instead the planet is orbiting the  component A, its mass is 2.26  with a semimajor axis of 2.02 AU.
