(6178) 1986 DA is a 2.3-kilometre-diameter M-type Mars-crosser and near-Earth asteroid notable for being significantly more radar-reflective than other asteroids. It is an Amor asteroid which means it approaches the orbit of Earth from the outside but does not cross it.Radar measurements suggest it is composed of nickel and iron and that it was derived from the center of a much larger object that experienced melting and differentiation.
