Omega Andromedae (ω And / 48 Andromedae / HD 8799)^[8] ye una estrella de magnitú aparente +4,83 asitiada na constelación d'Andrómeda. Alcuéntrase a 92 años lluz del Sistema Solar.

Omega Andromedae ye una subxigante blancu-mariella de tipu espectral F5IVe. Con una temperatura efectivo de 6581 K,^[9] ye 7,6 vegaes más lluminosa que'l Sol. A partir del so diámetru angular, 0,70 milisegundos d'arcu,^[10] puede envalorase el so verdaderu diámetru, siendo ésti 2,3 vegaes más grande que'l diámetru solar. Xira sobre sigo mesma con una velocidá de rotación igual o mayor de 57,1 km/s.^[9] Tocantes al so conteníu metálico, amuesa una metalicidá inferior a la del Sol ([Fe/H] = -0,16). Ye más masiva que la nuesa estrella —envalórase que la so masa ye casi un 50% mayor que la del Sol— y tien una edá averada de 2100 millones d'años.^[11]

Omega Andromedae forma un sistema binariu con una estrella 3,65 magnitúes más tenue. L'actual separación visual ente dambes componentes ye de 0,669 segundos d'arcu.^[12]
