Kepler-17
Sign in to saveKepler-17 is a main-sequence yellow dwarf star that is much more active than the Sun with starspots covering roughly 6% of its surface. Starspots are long-lived, with at least one persisting for 1400 days. ==Planetary system== The Kepler-17 is known to host one superjovian exoplanet, Kepler-17b, in orbit around it. It was discovered by the transit method in 2011.
