To put it more precisely, here's what I would like to do.

1.Create a stationary "sun" at point $\displaystyle X_c,Y_c,Z_c$

2.Create multiple "planets" at points $\displaystyle X_n,Y_n,Z_n$ where n is the number of the planet from 1 to infinity

3.Generate all of the necessary parameters to define each planet's orbit around the sun while only looking to avoid collisions at intersection points (if possible)

4.For each computer cycle, calculate the new position of each planet based on their calculated orbits

Can anyone lead me in the right direction?

Thanks,

Marc
