Uranus and Neptune are often called "ice giants." This is based on the theory that they were made from materials that easily freeze in space, like water and ammonia. However, this label does not come from direct observations, since no spacecraft has visited the two giants since Voyager 2 in the 1980s. Instead, it is drawn from computer models built using the planets’ sizes, masses, densities, and gravity fields. Now, a new study by scientists at the University of Zurich is challenging this idea. It suggests that the two planets may contain more rock than ice.

          They're colder because they are far away from the sun. I forgot the name of the hottest planet tho :l

            Also to counter myself Mercury isn't the hottest planet due to only being 800 degrees, Venus is 870

              Venus is the hottest planet because of the greenhouse gases in its atmosphere
