Kepler-182 is a star in the constellation of Cygnus. In the night sky, it is located at right ascension 19h 21m 39.2s and declination +38° 20′ 38″.[1] The star is notable for having two planets in the circumstellar habitable zone.[citation needed]

It has a radius of 1.146 R☉ and an effective temperature of 6,250 K.[2]

Two exoplanets orbit it. The first, Kepler-182b, has a radius of 0.23 RJ and orbits the parent star every 9.8 days. The second, Kepler-182c, has a radius of 0.306 RJ and orbits the parent star every 20.7 days.[2]
