What Is the Temperature of the Planet Uranus?

Uranus’ average surface temperature is -371.2 degrees Fahrenheit, making it the coldest planet in the solar system. One reason for this planet being so cold is that it has a low internal core temperature.

Uranus is an ice giant that does not consist of a solid surface. Its atmosphere has a composition that is mostly clouds made up of gases, such as hydrogen, helium and methane. Scientists believe that underneath this cloud layer there may be a liquid water layer and ice.
