Is there such a website showing the planets spinning and orbiting around the sun. I think this would help me more understand why we seem to see the Sun not spinning and so forth.

What you're looking for is called an orrery. Try this one:

Orrery: Solar System Simulation (http://www.cuug.ab.ca/~kmcclary/ORRERY/index.html)

You need the Java plug in to run the aplet, but it should offer to get it for you if you don't have it installed. That will take some time, but it is worth it.

The site has several models that you can run - pick the one labelled "70 planets and moons", but read the instructions first. To zoom in, click near the centre of the image, to zoom out, click near the edge. If the planets seem to move slowly to you, that&#39;s because they move slowly <G>. Try centering on Jupiter (or one of the other gas giants) and zoom in. Watching their moons gives you a real feel for how the close in ones whip around, and the farther out ones move so slowly.

Have fun.

You&#39;re certainly welcome. I spent a couple of entertaining hours playing with a few of the models on that site. Gives you a feel for just how chaotic orbital mechanics can be.

Another cool site is Solar System Live at .fourmilab.ch/cgi-bin/uncgi/Solar

It shows the positions of all the planets. You can play with the time display and get planetary positions at any date in history or the future.

For those of you who haven't seen this simulation, check it out! It is amazing.

Check out Neptune and look how far out Nereid actually orbits, and check out the Martian system and look at the sling-shot orbit of Phobos.

Very very interesting, and very very much worth a look, especially for those of you who haven't seen an orrery.
