http://phet.colorado.edu/simulations/si ... lar_System you can add planets and set rates, or use the preselected sets to watch 2d planetary orbit simulations. Newton, if only you could see this.

This is superb. I've seen a roughly similar one before, I think called gravity simulator. I would like to work out how to illustrate the orbits of the gas giants. There is a good one here with four stars in stable orbit. Moving the parameter for one just the slightest amount sends them haywire.

i spent like two hours on this the other day. Creating a new set of stable orbits that lasts for more than ten minutes is an interesting challenge.

I'm trying to simulate three planets around a star  See here. Will keep tinkering.

The sun is 99.8% of the mass of the solar system. If you make the three planets much more than 0.2% of the mass in total they become unstable.

seems like maybe we are the only two here nerdy enough to enjoy this, RT.

All other orbit animations wish they were this one. Seriously. http://www.wimp.com/earthyear/

I should have mentioned that I found this to be very cool as well.

I'm glad we are in good company!

There went my afternoon. I had a difficult time getting the third planet in there, I wish I had come back and read the rest of the forum before I spent all that time tinkering with it.... VERY cool, an awesome time killer to be sure

That is an awesome animation, johnson. Thanks for sharing. And add my name to the list of people spending way too much time with that simulator in the first post.

Pretty cool orbit animation that produces a tone every time a planet completes an orbit. Makes interesting "solar song". http://www.whitevinyldesign.com/solarbeat/

That is way cool. It really shows how slow Pluto's orbit is compared with the inner planets.

Nice, that was pretty, kind of like a music box, with a rng.
