Planetary systemThree 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] {{OrbitboxPlanet begin| name = Kepler-65 | table_ref= }}{{OrbitboxPlanet | exoplanet = b | mass = | period = 2.154910 | semimajor = 0.035 | eccentricity = | inclination = 79.07 | radius_earth = 1.42}}{{OrbitboxPlanet | exoplanet = c | mass_earth = <20 | semimajor = 0.068 | period = 5.859944 | eccentricity = | inclination = 83.65 | radius_earth = 2.58 }}{{OrbitboxPlanet | exoplanet = d | mass_earth = 2 | semimajor = 0.084 | period = 8.131146 | eccentricity = | inclination = 84.8 | radius_earth = 1.52 }}{{Orbitbox end}} External links
