Kepler-25c is an exoplanet orbiting the star Kepler-25, located in the constellation Lyra.[4] The planet was first detected as a candidate extrasolar planet by the Kepler space telescope in 2011.[5] It was confirmed, in 2012, by Jason Steffen and collaborators using transit-timing variations obtained by the Kepler Space Telescope.[1] It orbits its parent star at only 0.110 astronomical units away, and at its distance it completes an orbit once every 12.7 days.[1]
