Kepler-452 b is a Super-Earth exoplanet (a planet larger than Earth but smaller than Neptune), about 1.6 times the radius of Earth. With an equilibrium temperature of 265 K (-8°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 1.1 Earth years. It was discovered in 2015 using the transit method. It orbits the G-type star Kepler-452, located approximately 552 parsecs (1799 light-years) from Earth.
