Saturn's average surface temperature is a frigid -288 degrees Fahrenheit (-178 degrees Celsius). The planet does not have a solid surface like Earth but rather a thick atmosphere made mostly of hydrogen and helium.
The average temperature on Jupiter varies greatly depending on the location on the planet. In the upper atmosphere, temperatures can be around -145 degrees Celsius (-234 degrees Fahrenheit) during the day and -185 degrees Celsius (-301 degrees Fahrenheit) at night. However, closer to the core of the planet, temperatures can reach tens of thousands of degrees Celsius.
Uranus, with an average temperature of -355 degrees Fahrenheit and -215 degrees Celsius.
The temperature range on Uranus is typically between -224 to -370 degrees Celsius (-371 to -694 degrees Fahrenheit) in its outer atmosphere. The colder temperatures are due to the planet's distance from the Sun and its lack of internal heat sources.
Mars. The temperature there can vary between 20 degrees Celsius and -140 degrees Celsius.
Jupiter's temperature in its upper atmosphere is approximately -145 degrees Celsius (-234 degrees Fahrenheit) during the daytime. However, deeper within the atmosphere, the temperature can reach thousands of degrees due to the intense pressure.
There is no known planet with that temperature (or even temputure) range.
The difference is approx 660 Celsius degrees.
