11 Aquarii (11 Aqr / HD 199960 / HR 8041)^[8] ye una estrella de magnitú aparente +6,21 encuadrada na constelación d'Acuariu. Alcuéntrase a 86 años lluz del Sistema Solar.

Coordenaes: 21^h 0^m 33.841^s, -4^° 43^′ 48.935^″

11 Aquarii ye una nana mariella asemeyada en munchos aspeutos al nuesu Sol. De tipu espectral G1V,^[8] tien una temperatura superficial de 5973 ± 26 K,^[9] cuasi 200 K superior a la solar. La so lluminosidá perpasa a la del Sol nun 86%^[9] y tamién el so diámetru ye daqué más grande que'l diámetru solar —en redol a un 30% mayor—,^[10] xirando sobre sigo mesma con una velocidá de rotación proyeutada de 3,0 km/s.^[11] Con una masa averada igual a 1,2 mases solares, nun esiste consensu tocantes a la so edá: dellos estudios señalen cifres entendíes ente los 4400 y los 6300 millones d'años.^[10]^[12]

11 Aquarii presenta un índiz de metalicidá más eleváu que'l del Sol ([Fe/H] = +0,25). Tolos elementos químicos evaluaos son más abondosos que na nuesa estrella, siendo l'aluminiu'l qu'exhibe una diferencia más acusada; el so conteníu relativo ye 2,5 vegaes más abondosu que nel Sol.^[13]
