Double star catalogues list two stars as optical companions. One has a magnitude of 10.9 and is separated by 16.9 arcseconds. It has been suggested it is related to the primary, but parallax measured by Gaia yields a much greater distance for this star in comparison to HD 16028. The other is even fainter and is separated 45 arcseconds from the primary.
