I found this a couple of days ago from Play This Thing.

Smash planets together, introduce rogue stars, and build new worlds from spinning discs of debris. Fire a moon into a planet or destroy everything you've created with a super massive black hole.

You can simulate and interact with:

* Our solar system: the 8 planets,160+ moons, and hundreds of asteroids
* Nearest 1000 stars to our Sun
* Our local group of galaxies
* An unlimited number of fictional scenarios

Tinker with your creation or sit back and watch the effects of gravity unfold. It's fun, accessible, and easy to use.

It's pretty fun to play around with. The trial version allows you to play around for 60 minutes before locking out some features. I'm not sure what the exact term is, but the software appears to be (required) donationware to me. You can pay whatever you think it's worth to you for a personal license. If your payment is $25 or more then he will send you a pair of Red & Blue 3D glasses which can be used with this software.

Be sure to check out the video!
