The free screensaver, The Modern Planet Uranus, was created by RateMyScreensaver.com and contains 22 high resolution images of the Uranus. Uranus, meaning heaven or sky is the seventh planet from the Sun. It is a gas giant, the third largest by diameter and fourth largest by mass. It is named after Uranus, the Greek god of the sky and progenitor of the other gods. Uranus is the first planet discovered in modern times. Sir William Herschel formally discovered the planet on March 13, 1781; the other planets (from Mercury out to Saturn) have been known since ancient times, since they are visible to the naked eye. Uranus' discovery expanded the boundaries of the solar system for the first time in modern human history. It was also the first planet discovered using technology (a telescope) rather than the naked eye. - wiki Screensaver Picture Count: 22 Screensaver Type: Slideshow Credit: All images in this screensaver provided by NASA and the ESA
