It’s almost impossible to say what is the temperature of Saturn. The highest cloud tops, right at the edge of space, are colder than -150 Â°C. But as you travel down into the planet, pressures and temperatures rise. At the very core, temperatures can reach 11,700 Â°C.

As I mentioned above, the internal core of Saturn gets as high as 11,700 Â°C. This comes from the huge amount of hydrogen and helium compressing down and heating up the core.
Saturn actually generates heat. In fact, it’s putting out 2.5 times as much energy as it receives from the Sun. This is because the planet’s gravity is slowly compressing it down, and generating heat as it does this.
Once you reach the cloud layers in Saturn’s atmosphere, temperatures drop quickly. The bottom of the clouds are made of water ice and have an average temperature of -23 Â°C. Above this is a layer of ammonium hydrosulfide ice, with an average temperature of -93 Â°C. Above this are the ammonia ice clouds that give Saturn its orange/yellow color. Temperatures at the very edge of Saturn can get as low as -150 Â°C.
