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

Planetary system

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.^[2]
