Saturn's Temperature Ranges

Saturn is the sixth planet from the sun.

If you're planning a trip to Saturn, don't forget your coat because it is one cold planet. As a gas planet, Saturn has a wide range of temperatures, but, according to NASA, the effective temperature of the planet is a frigid -178 degrees Celsius (-288 degrees Fahrenheit). On the other hand, temperatures in the lower layers of the planet's atmosphere can climb as high as 57 degrees Celsius (134 degrees Fahrenheit). To put this in perspective, water freezes at zero degrees Celsius (32 degrees Fahrenheit).

Saturn, the Sun and Temperature

Saturn is 1.43 billion kilometers (more than 880 million miles) from the sun. This means the rays of light from the solar system's big ball of fire don't scorch Saturn's surface as intensely as they do when they heat up the Earth. In fact, most of Saturn's heat comes from planet's core instead of the sun. The planet's core temperature is believed to be as high as 11,700 degrees Celsius (21,000 degrees Fahrenheit), and this icy planet actually radiates twice as much heat into space as it receives from the sun.
