Shooting Stars Screensaver - Version 1.1 The free screensaver, Shooting Stars, was created by RateMyScreensaver.com and contains 20 high resolution images of Comets. A comet is a small body in the solar system that orbits the Sun and (at least occasionally) exhibits a coma (or atmosphere) and/or a tail - both primarily from the effects of solar radiation upon the comet's nucleus, which itself is a minor body composed of rock, dust, and ice.
