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. How about having the opportunity to watch this unique planet any time you like? All you need is this terrific Planet Uranus 3D Screensaver on your desktop!
