  The solar analogs 16 Cyg A and 16 Cyg B are excellent asteroseismic targets
in the \Kepler field of view and together with a red dwarf and a Jovian planet
form an interesting system. For these more evolved Sun-like stars we cannot
detect surface rotation with the current \Kepler data but instead use the
technique of asteroseimology to determine rotational properties of both 16 Cyg
A and B. We find the rotation periods to be $23.8^{+1.5}_{-1.8} \rm \, days$
and $23.2^{+11.5}_{-3.2} \rm \, days$, and the angles of inclination to be
$56^{+6}_{-5} \, ^{\circ}$ and $36^{+17}_{-7} \, ^{\circ}$, for A and B
respectively. Together with these results we use the published mass and age to
suggest that, under the assumption of a solar-like rotation profile, 16 Cyg A
could be used when calibrating gyrochronology relations. In addition, we
discuss the known 16 Cyg B star-planet eccentricity and measured low obliquity
which is consistent with Kozai cycling and tidal theory.
