hi

I'm currently looking at how to simulate easily some stellar systems (meaning some central stars and then some planets with maybe satellites), in order to allow later some space based strategy game (hence with space ships moving around). This should all be based around time (so the state of each system differs through time)

I'm quite struggling with the math behind this topic, like for example:
- ellipse related math,
- creating the path from planet A to B having time in mind (respective positions will change over time)...

Do you know of any resources for that ? I wouldn't mind even buying books about it...

thanks in advance

side note: how to display all this stuff isn't a matter at this point in time, I'll simple plans for that (basically sticking to 2D and a "high level view" with no space ships/planets details, just markers)
