Two wonderful animations of the solar system I found..

The first one: http://www.solarsystemscope.com/scope.swf

You can change the zoom (on the right), or the perspective (on the left), set the planets in motion (at the bottom, the normal speed is about 1 day per second I think), and also click on a planet to zoom on it or know the distance to another object (in AU, Astronomical unit, which is the average distance between the Erath and the Sun, about 150 millions kilometers).. if you hover the mouse on a star you'll see its name and its distance to the solar system in light years (1 ly = 64.000 AU approximately).. I haven't checked all the options yet though..

The second one has some additional options (and other missing ones): SunAeon

You can control the speed better.. when you zoom on a planet you have additional information, as well as the possibility to look into the internal structure of the planet..

Anyways, explore the options, and enjoy yourselves..
