19 Aquilae (19 Aql)^[8]^[9] ye una estrella de magnitú aparente +5,23 na constelación del Águila. Alcuéntrase, d'alcuerdu al nuevu amenorgamientu de los datos de paralax del satélite Hipparcos, a 149 ± 4 años lluz de distancia del Sistema Solar.

19 Aquilae ye una xigante o subxigante blanca de tipu espectral F0III-IV.^[8] La so temperatura efectivo ye de 6886 K^[10] y la so lluminosidá ye unes 13 vegaes superior a la del Sol. Tien una masa un 69% mayor que la masa solar y la so edá envalórase en 1300 millones d'años.^[11] Xira sobre sigo mesma con una velocidá de rotación igual o superior a 57 km/s.^[12]

19 Aquilae amuesa un conteníu metálico que, en llinies xenerales, ye asemeyada al del Sol ([Fe/H] = -0,06). Sicasí, evidencia ciertu empobrecimientu de manganesu y circoniu y, nel otru estremu, sobreabundancia d'elementos como bariu, escandiu y praseodimiu; esti últimu elementu del grupu de les tierres rares ye cuasi cinco veces más abondosa que nel nuesu Sol ([Pr/H] = +0,68).^[13] Coles mesmes, evidencia una bayura relativa de litiu claramente cimeru a la solar (A(Li) = 2,83), pero que ta na media de la bayura cósmica d'esti metal.^[14]
