Orbital equations, and power required to run them

Due to a discussion on the SO IRC today, I'm curious about orbital mechanics, and The equations needed to solve orbital problems The computing power required to solve complex problems The question in particular is calculating when the Earth will plow into the Sun (or vice versa, depending on the frame of reference). I suspect that a...

Mathematica: How to use a single equation with multiple parameters to calculate any parameter

Hi, Currently I use a single equation with different combination of known/unknown parameters. As I don't have any fancy calculator it would be much easier to define the equation in Mathematica and passing known parameters to calculate unknown values. I would be very thankful if anyone of you could give an example solution (if possible ...
