Is Uranus colder than Earth?
Uranus is the coldest planet in the solar system, with a minimum temperature of 49K (-224.2 degrees Celsius). Its atmosphere is mostly hydrogen and helium, with a small amount of methane that gives it a blue-green color.
In fact, Uranus's heat flux is only 0.042 ± 0.047 W/m 2, which is lower than the internal heat flux of Earth of about 0.075 W/m 2. The lowest temperature recorded in Uranus's tropopause is 49 K (−224 °C), making Uranus the coldest planet in the Solar System, colder than Neptune.
The lowest temperature recorded in Uranus's tropopause is 49 K (−224.2 °C; −371.5 °F), making Uranus the coldest planet in the Solar System.

3 days ago · On average, Uranus radiates the same amount of energy as an ideal, perfectly absorbing surface at a temperature of 59.1 kelvins (K; −353 °F, −214 °C). Temperature decreases with decreasing pressure—i.e., with increasing altitude, where it is about 52 K (−366 °F, −221 °C), the coldest temperature in Uranus’s atmosphere.
