Saturn's atmosphere is actually quite cold, with an average temperature of -178 degrees Celsius. However, the planet does have a warm interior, with temperatures reaching up to 11,700 degrees Celsius at its core. This heat is generated by the planet's gravitational compression and the radioactive decay of elements such as uranium and thorium.

Saturn's atmosphere is also heated by the Sun, but this only affects the upper layers of the atmosphere. The lower layers are heated by the planet's internal heat, which is why the temperature of the atmosphere increases as you move closer to the planet's surface.

Saturn's warm interior also drives the planet's powerful winds. These winds can reach speeds of up to 1,800 kilometers per hour and are responsible for the planet's distinctive banded appearance.
