There are many planets with temperatures more than a thousand degree Celsius which is the temperature of their surfaces only. The crust temperature is not known yet. But this planet Gaze is a lone warrior in the war of heat. It is so far the coldest planet existing in the universe with a temperature of -200 Degree Celsius. It is also among the most remote exoplanet as it is quite faraway from Earth. It is 28,000 lights years away from Earth. It takes around 10 Earth years to complete an orbit. But the interesting thing is that its star is a lot smaller in size as compared to the star of Earth.
