Kepler-25 is a star in the northern constellation of Lyra. It is slightly larger and more massive than the Sun, with a luminosity 2 times that of the Sun. With an apparent visual magnitude of 10.6, this star is too faint to be seen with the naked eye. thumb|

==Planetary system== In 2011, two candidate planets were found transiting this star by the Kepler space telescope. These planets are very close to yet not lie in the 1:2 orbital resonance to each other, indicating the absence of other planetary objects in the inner part of the planetary systems. These planets were confirmed through transit-timing variation method. A third planet was discovered through follow-up radial velocity measurements and was confirmed in January 2014.
