Kepler-69 c is a Super-Earth exoplanet (a planet larger than Earth but smaller than Neptune), about 1.7 times the radius of Earth. With an equilibrium temperature of 299 K (26°C), it lies within the habitable zone where liquid water could potentially exist on its surface. The planet completes one orbit around its star every 242.5 Earth days. It was discovered in 2013 using the transit method. It orbits the G-type star Kepler-69, located approximately 731 parsecs (2383 light-years) from Earth.
