HD 176051
Encyclopedia
HD 176051 is a spectroscopic binary star system located 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.
If the planet is orbiting the 1.07 Solar mass A component, the planet mass is 2.26 MJ and a = 2.02 AU.
Earth
Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets...

Orbital eccentricity
The orbital eccentricity of an astronomical body is the amount by which its orbit deviates from a perfect circle, where 0 is perfectly circular, and 1.0 is a parabola, and no longer a closed orbit...
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
The parent star is a binary star. The planet parameters are given for the 0.71 Solar mass B component (Muterspaugh et al. 2010).If the planet is orbiting the 1.07 Solar mass A component, the planet mass is 2.26 MJ and a = 2.02 AU.
