HAT-P-11, also designated GSC 03561-02092, is an orange dwarf metal rich star about 123 light-years away in the constellation Cygnus. This star is notable for its relatively large rate of proper motion. The magnitude of this star is about 9, which means it is not visible to the naked eye but can be seen with a medium-sized amateur telescope on a clear dark night. The age of this star is about 6.5 billion years. The star has active latitudes that generate starspots. The star appears to have a very small radius, which can be explained by the anomalously high helium fraction.

(en) HAT-P-11, également appelée GSC 03561-02092 voire Kepler-3, est une étoile de magnitude visuelle 9,6 située à environ ∼123 a.l. (∼37,7 pc) du Système solaire, dans la constellation du Cygne. Cette naine orange de type spectral K4 V a une métallicité double de celle du Soleil et est un peu plus âgée que ce dernier. Elle a comme particularité de posséder un mouvement propre significatif, de 263,91 mas·an-1. Une exoplanète de type Neptune chaud, appelée HAT-P-11 b, a été détectée autour de cette étoile en janvier 2009 par la méthode des transits. (fr) HAT-P-11は、はくちょう座の方向に約120光年離れた距離にある10等級の恒星である。太陽と比べ一回り小さいスペクトル分類K4V型のK型主系列星で、光度は太陽の4分の1程度である。2020年時点で、2個の太陽系外惑星が周囲を公転していることが知られている。 (ja) HAT-P-11, também designada GSC 03561-02092, é uma estrela anã laranja rica em metais a cerca de 123 anos-luz de distância da Terra na constelação de Cygnus. Esta estrela é notável pela sua relativamente grande taxa de movimento próprio. A magnitude desta estrela é de cerca de 9, o que significa que não é visível a olho nu, mas pode ser vista com um telescópio amador de tamanho médio em uma clara noite escura. A idade desta estrela é cerca de 6.5 bilhões de anos. A estrela tem latitudes ativas que geram manchas estelares. (pt) HAT-P-11 (Kepler-3) — звезда, которая находится в созвездии Лебедя на расстоянии около 123 световых лет от нас. Вокруг звезды обращается, как минимум, одна планета. (ru) HAT-P-11，又称GSC 03561-02092，是一颗位于天鹅座的橙矮星，距离地球123光年，它因为其自行速度快而出名。视星等为9.5，裸眼不能看到它，但通过望远镜可以见到。HAT-P-11的年龄是65亿年。 2009年，匈牙利自动望远镜网络计划发现这颗恒星有一颗行星（HAT-P-11b）。这个行星系统的具体参数如下： (zh)
