Algodoo

cool!

The path of an object in orbit varies inversely to how close it is to the parent body. The laser, regardless of what velocity you set it to, will still hold a constant velocity throughout the trajectory. That's what I've been trying to tell you, that with single laser, such a thing is not possible. It's cool, but it can never be generally accurate.

This is essentially "Rocket Science" and is way beyond my understanding, but I found a web site which might be helpful to you: Orbiting Satellite Math

ksp in algodoo is getting real

I haven't seen any KSP (the video game) here on Algobox. Have you?

I made one

Thanks Xray, but I believe when seeing these formulas, I understood that the coding would be too complicated for me ...
