Kepler-65 is a star slightly more massive than the Sun and has at least three planets.

Planetary system[edit]

Three planets were announced in 2013. All three planets orbit very close to their star. Follow-up radial velocity measurements provided data too noisy to constrain the mass of planets.[1] Follow-up transit-timing variation analysis helped to measure the mass of Kepler-65d which revealed that it has significantly lower density than Earth.
