Free Astronomy software that lets me create my own theoretical Solar System?
And then calculate events such as solar eclipses and moon phases? Would anyone know of a program like that or at least a way to try and find a program like that?
Additional Details
I need something that will allow for the formulation of a calender for the various Planets, which includes the lunar phases of various Moons for each planet and will allow me to view them in Orbit at any set date on the solar calender created for the system. I also need one that does most of the advanced physics and mathematics for me as I am not skilled or talented in those areas. Think something for the education of an average high school student or general layperson.
I am the only one in my high school to take an independent study in astronomy. At college, I took the basic astronomy class and was a lab assistant at the same time which had plenty of students doing a double take. Also had to give a lecture because the professor was ill and had a physics professor assisting me. It turned out that he was hiding nearby. I have not heard of a program for a make believe planetary system. Google Earth has extras like zooming in on The Moon/Mars/etc. Go surfing.

I would just call up astronomy departments at universities and ask this question to the professors. Track down an observatory. They would love to talk your ear off on it.
