HD~59686 is a single-lined moderately close ($a_{B} = 13.6\\,$AU) eccentric ($e_{B} = 0.73$) binary, where the primary is an evolved K giant with mass $M = 1.9 M_{\\odot}$ and the secondary is a star with a minimum mass of $m_{B} = 0.53 M_{\\odot}$. Additionally, on the basis of precise radial velocity (RV) data a Jovian planet with a minimum mass of $m_p = 7 M_{\\mathrm{Jup}}$, orbiting the primary on a nearly circular S-type orbit with $e_p = 0.05$ and $a_p = 1.09\\,$AU, has recently been announced.
