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 MJup and a = 2.02 AU. Currently the hypothesis of the secondary star as exoplanet host is favoured.

22 Oct 2010: The parent star is part of a binary system very similar to α Centauri (P = 22430 d, a = 19 AUs, e = 0.266, i = 114.16°).
Muterspaugh et al. (2010) are not certain about which component the planet b, detected by astrometry, is orbiting, although the secondary star is more favoured as host.
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.
