Saturn's average temperature is minus 288 degrees Fahrenheit, or minus 178 degrees Celsius. While there is some temperature variation between the poles and the equator, Saturn's temperature is fairly consistent since much of its heat comes from the planet's interior rather than the sun.
There are three layers of clouds on Saturn, with the inner layers being increasingly warmer. The outer layer's temperature ranges from -280 to -170 degrees Fahrenheit, or -173 to 113 degrees Celsius. The middle layer maintains temperatures of -127 to 26 degrees Fahrenheit, or -88 to -3 Celsius, while the inner layer gets as warm as 134 degrees Fahrenheit, or 57 degrees Celsius. The rocky core may reach temperatures of up to 21,000 degrees Fahrenheit, or 11,700 degrees Celsius.
