In the context of recent Flash-related discussions and the usage of
open Web standards, I searched for 'animation SVG "solar system"' and
discovered this example:

http://www.svgelves.com/svg/L_chrisa_02.svg

Sadly, it only works in Opera amongst the browsers I have. Konqueror
displays the initial frame but doesn't animate the scene, although
later versions of that browser might support animation. I have an old
version of Firefox which doesn't support SVG at all.
