It's a screensaver that, by means of a 3 dimensional animation, manages to take us through the planetary system in which we live, showing us each one of the planets and satellites that form it, as well as the Sun, of course.
Once the screensaver is activated we will hear background music while we see some of the details of each of the elements. We will also have the option to add a clock that will indicate exactly what time it is. Each planet and satellite si designed to follow its real trajectory, showing its dimensions and exact speed.
If you want to see the Solar System each time your screensaver activates, you have to try out Solar System 3D Screensaver.
