Gliese 435 (GJ 435 / HD 101581 / HIP 56998)^[6] ye una estrella de magnitú aparente +7,75 na constelación de Centauru, distante 40,8 años lluz del Sistema Solar. Ente les estrelles más cercanes a Gliese 435 ta Gliese 431; el sistema estelar HD 102365 alcuéntrase a daqué menos de 11 años lluz d'ella.^[7]

Coordenaes: 11^h 41^m 2.468^s, -44^° 24^′ 18.682^″

Gliese 435 ye una nana naranxa de tipu espectral K4.5V.^[6] Más fría que'l Sol —la so temperatura superficial ye de 4740 ~ K— relluma con una lluminosidá equivalente al 14% de la lluminosidá solar.^[8] De carauterístiques físiques similares a les de ε Indi —pero cuatro vegaes más alloñada qu'ésta—, tien el 67% de la masa solar y el so diámetru correspuende al 65% del que tien el Sol.^[9] Xira sobre sigo mesma con una velocidá de rotación proyeutada de 5,0 km/s.^[10]

Anque nun esiste unanimidá tocantes a la so metalicidá, lo que si ta claro que ye bien inferior a la solar. Una fonte señala un índiz de metalicidá de [Fe/H] = -0,52,^[8] ente qu'otra amenorga esti parámetru a [Fe/H] = -0,93; esta última cifra supondría una bayura relativa de metales en redol al 12% de l'atopada nel Sol.^[11]
