Gliese 204 (GJ 204 / HD 36003 / HIP 25623)^[6] ye una estrella de magnitú aparente +7,64 asitiada a 42,4 años lluz del Sistema Solar. Ta encuadrada na constelación d'Orión visualmente 1,5º al sureste de η Orionis.

Coordenaes: 5^h 28^m 26.095^s, -3^° 29^′ 58.397^″

Gliese 204 ye una nana naranxa de tipu espectral K5V,^[6] una estrella de la secuencia principal que llogra la so enerxía a partir de la fusión del hidróxenu. Más fría que'l Sol —la so temperatura superficial ye de 4647 ± 88 K— relluma con una lluminosidá equivalente al 18% de la lluminosidá solar.^[7] De carauterístiques físiques similares a les de ε Indi, pero casi cuatro veces más alloñada qu'ésta, tien ente'l 60 y el 75% de la masa solar.^[8]^[7] El so diámetru correspuende al 70% del que tien el Sol.^[8]

Nun esiste consensu tocantes a la composición química de Gliese 204. El valor del so índiz de metalicidá —entendiendo por metales aquellos elementos que son más pesaos que'l heliu— asitiar ente [Fe/H] = +0,09^[9] y [Fe/H] = -0,44,^[10] en función de la fonte consultada.
