Kepler-725

Kepler-725 is a Sun-like star located about away in the constellation of Lyra. At an apparent magnitude of 15.1, it is too faint to be seen with the naked eye. It has a spectral type of G9V, which classifies it as a yellow dwarf star.

Planetary system

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. The non-transiting planet Kepler-725 c was found in 2025 via the transit-timing variation method and has a mass of about 10 times Earth mass. This planet receives an average insolation 1.4 times that of Earth, varying depending on its position in its eccentric orbit. 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.
Another planetary candidate with a period of 5.7 days, designated KOI-918.02, is a false positive.
