Alpha Herculis is a triple star system.  The primary (brightest) of the three stars, designated α<sup>1</sup> Herculis or α Herculis A, is a pulsating variable star on the [[asymptotic giant branch]] (AGB). The primary star forms a visual binary pair with a second star, which is itself a spectroscopic binary.<ref name=moravveji/>

Alpha Herculis also forms the A and B components of a wider system <!-- system? --> designated WDS&nbsp;J17146+1423, with two additional faint [[double star|visual companions]] designated WDS&nbsp;J17146+1423C and D.<ref name="WDS"/>  The two fainter stars are far more distant than the triple system.<ref name=dr2cd/>
