HD 16028 is a star in the constellation Andromeda. Its apparent magnitude is 5.71.[2] Located approximately Script error: No such module "convert". distant,[1] it is an orange giant of spectral type K3III,[3] a star that has used up its core hydrogen and has expanded.
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,[3] but parallax measured by Gaia yields a much greater distance for this star in comparison to HD 16028.[6] The other is even fainter and is separated 45 arcseconds from the primary.[7]
