Explore the Solar System with a Dynamic Simulator for Teaching - Free Download

Hi
Is there a software in which I can for example change the orbit or angular velocity of the moon and observe it's effects on Earth's daytime/nighttime?
I want to use it for teaching so I need it to be visual.

thanks.

Perhaps you would be interested in NASA's Solar System Simulator (free) or Stellarium (free, open source).

You can also use the universe sandbox.
