Kepler-22 b is a Neptune-like exoplanet (an ice giant with a thick atmosphere), about 2.1 times the radius of Earth. With an equilibrium temperature of 279 K (6°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 289.9 Earth days. It was discovered in 2011 using the transit method. It orbits the star Kepler-22, located approximately 195 parsecs (635 light-years) from Earth.
