Planet Uranus 3D Screensaver v1.1 (2.38 MB)
Uranus is unique in our solar system because it is tilted 98 degrees. When viewed from Earth, it appears
to rotate on its side! At different times throughout its orbit, we can actually view one of the planet's poles
head-on. The atmosphere is composed of hydrogen, helium, and methane. The temperature in the upper
atmosphere is so cold that the methane condenses and forms a thin cloud layer which gives the planet its
blue-green appearance. Uranus is the farthest planet from Earth that can be seen with the unaided eye but
of course this can only happen on a clear, dark night.
