Remarks
22 Oct 2010: The parent star is a binary star.Muterspaugh et al. (2010) do not known around which component the planet b, detected by astrometry, is orbiting.
The two components are
- HD 176051A (1.07 Solar mass F9V star, V = 5.28) alias GJ 738 A
- HD 176051B (0.71 Solar mass K1V star, V = 7.82), alias GJ 738 B
We therefore take the (rather artificially) mean value (MA + MB)/2 for the stellar mass.

Remarks
22 Oct 2010: 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.
