Kepler-25 is a star in the northern constellation of Lyra. It is located at the celestial coordinates: Right Ascension 19h 06m 33.2204s Declination +39° 29′ 16.321″ 19h 21m 39.0s,. With an apparent visual magnitude of 10.7, this star is too faint to be seen with the naked eye.
In 2012, two planets were found transiting the star. These planets were confirmed through transit-timing variation method. A third planet was discovered through follow-up radial velocity measurements which was confirmed in January 2014.
