Kepler-438
Sign in to saveKepler-438 is a red dwarf in the constellation Lyra, about 590 light years from Earth. It is notable for its planetary system, which includes Kepler-438b, a possibly Earth-size planet within Kepler-438's habitable zone. Kepler-438 is a flare star that undergoes random, dramatic increases in brightness due to flare activity. It emits strong superflares every few hundred days, with each flare being stronger than the most powerful flare recorded on the Sun.

Kepler-438 is a red dwarf in the constellation Lyra, about 590 light years from Earth. It is notable for its planetary system, which includes Kepler-438b, a possibly Earth-size planet within Kepler-438's habitable zone. Kepler-438 is a flare star that undergoes random, dramatic increases in brightness due to flare activity. It emits strong superflares every few hundred days, with each flare being stronger than the most powerful flare recorded on the Sun.
==Planetary system== The system has one confirmed planet. However, transit timing observations of Kepler-438b indicate the possible presence of additional planets.
