Gamma Pavonis (γ Pav / HD 203608 / HR 8181)^[8] ye una estrella na constelación de Pavu de magnitú aparente +4,22. Alcuéntrase a namái 30,1 años lluz del Sistema Solar, siendo Gliese 877, a 6,6 años lluz, la estrella más cercana a Gamma Pavonis.^[9]

Coordenaes: 21^h 26^m 26.605^s, -65^° 21^′ 58.313^″

Gamma Pavonis ye una nana mariella de tipu espectral F8V y 6070 K de temperatura. Dalgunes de les sos carauterístiques físiques son relativamente paecíes a les del Sol: la so lluminosidá ye un 50% mayor que la solar, el so radiu ye un 10% más grande que'l del Sol y tien una masa de 0,8 mases solares.^[9] Al igual que la nuesa estrella, amuesa una baxa velocidá de rotación proyeutada de 2,4 km/s.^[10] Otra manera, la so metalicidá —basada na so bayura en fierro— paez ser namái ente un 12 y un 25% de la solar. La so edá envalórase en 7250 ± 70 millones d'años,^[11] notablemente mayor que la del Sol. Tien un altu momentu angular alredor de la galaxa, lo que llevó a pensar que pue ser una vieya estrella del discu galácticu,^[12] magar otros autores considerar una estrella del discu finu.^[13]

Gamma Pavonis amuesa un escesu nel infrarroxu que s'atribúi a la presencia de polvu circumestelar calecíu pola mesma estrella.^[11] Ocupa'l númberu 14 ente les 100 estrelles escoyíes pol Terrestrial Planet Finder (TPF) pa la busca de planetes terrestres.^[14]
