kepler 22b

Kepler-22b is a planet orbiting in the habitable zone of its sun-like star, Kepler-22, which is located roughly 600 light-years from Earth. With a radius of about 2.4 times that of Earth, astronomers noted after its discovery in 2011 that the planet's temperatures about the same. If the greenhouse effect is the same as well, scientists estimated its surface temperature is a life-friendly 72 degrees Fahrenheit 22 degrees Celsius
