Kepler-22b is an exoplanet that was discovered by NASA's Kepler Space Telescope in 2011. It is located about 600 light-years from Earth in the constellation Cygnus. The planet is about 2.4 times the size of Earth and has a surface temperature of about 72 degrees Fahrenheit (22 degrees Celsius), which is similar to Earth's average temperature. It is thought to be located in the habitable zone of its star, which means that it could potentially have liquid water on its surface and could potentially support life as we know it. However, much more research would be needed to confirm this possibility.
