Temperatures in Saturn's atmosphere increase along with pressure the closer one travels to the center. As a giant gas planet, Saturn doesn't have solid ground; scientists set the surface of the planet at the point where pressure is equal to that of sea level on Earth. Saturn contains three layers of clouds.The upper layers of ammonia ice have temperatures ranging from minus 280 F (minus 173 C) to minus 170 F (113 C).he interior may reach temperatures of up to 21,000 F (11,700 C). Because the distance to Saturn from the sun averages 886 million miles (1.4 billion kilometers), most of the planet's heat comes from its core. Saturn radiates more than twice as much heat into space as it receives from the sun.
