Kepler-725 has two confirmed planets. The transiting planet Kepler-725 b was discovered in 2016 and is a gas giant with orbital period of 40 days.[6] The non-transiting planet Kepler-725 c was found in 2025 via the transit-timing variation (TTV) method and has a mass of about 10 times Earth mass.[4][7] This planet receives an average insolation 1.4 times that of Earth, varying depending on its position in its eccentric orbit.[7] It is the first super-Earth partially in the habitable zone to be discovered via the TTV method, and the only known super-Earth in the habitable zone of a Sun-like star with a measured mass (that is not a minimum mass).[4]
Another planetary candidate with a period of 5.7 days, designated KOI-918.02, is a false positive.[8]
