Gliese 349 (GJ 349 / HD 82106 / HIP 46580)^[7] ye una estrella de magnitú aparente +7,22. Ta encuadrada na constelación d'Hidra cerca de la llende con Lleo, a pocu más de 2º de 10 Leonis. Tópase asitiada a 41,4 años lluz del Sistema Solar. La nana colorada Gliese 361 alcuéntrase a 7 años lluz d'ella.^[8]

Coordenaes: 9^h 29^m 54.825^s, 5^° 39^′ 18.479^″

Gliese 349 ye una nana naranxa de tipu espectral K3V,^[7] 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 4419 K—^[9] relluma con una lluminosidá nel espectru visible equivalente al 18% de la lluminosidá solar.^[10] De carauterístiques físiques similares a les de ε Indi, pero casi cuatro veces más alloñada qu'ésta, tien el 79% de la masa solar y el so diámetru correspuende al 73% del que tien el Sol.^[11]

Gliese 349 xira sobre sigo mesma con una velocidá de rotación proyeutada de 4,1 km/s,^[9] siendo'l so periodu de rotación de 13,30 díes. Estos valores dexen envalorar la so edá por xirocronoloxía, amosando que Gliese 349 ye una nueva estrella de 435 millones d'años d'edá.^[12] El so índiz de metalicidá ([Fe/H] = -0,15), revela un conteníu metálico —entendiendo por metales aquellos elementos más pesaos que'l heliu— inferior a la solar.^[13]
