HD 16004 je zvezda v severnem ozvezdju Andromeda. Zvezda je pravi izziv za opazovanje s prostim očesom tudi pod izvrstnimi pogoji, saj ima navidezno magnitudo enako 6,26.^[2] Nahaja se približno 202 pc (660 ly) stran od nas, a bliža se nam s stalno heliocentrično radialno hitrostjo -6,8 km/s.^[3] To je kemijsko nepravilna Hg-Mn zvezda^[8] z zvezdno klasifikacijo B9.5 III HgMn.^[2]
