Because Saturn's atmosphere consists of three different layers, the temperature ranges can vary from layer to layer. At the uppermost layer, temperatures can range from nearly -283 to -171 degrees Fahrenheit. The following layer has a temperature range from around -127 to 26 degrees, and the bottom layer temperature may reach as high as 134 degrees.
Although these are the temperature ranges for the different atmospheric layers on Saturn, this planet's core temperature can be as high as 21,000 degrees. Saturn has a rocky core.
Saturn is one of the gas giant planets with an atmosphere composed of mainly hydrogen and helium. With a diameter of nearly 75,000 miles, Saturn is the second biggest planet. Saturn has many moons, including Titan, Rhea, Mimas and Iapetus.
