I disagree that it is a bad idea however I will admit it is not the most practical approach, also, how much of a bad idea it is depends on the project really. It is entirely possible to obtain stable orbits and I have achieved just that, I didn’t encounter any precision issues and maintained ~120 fps with >12 orbiting bodies, none of which collided with each other or the central body. I’ll admit it was no easy task to obtain stability, especially for >12 bodies, but once I had achieved it the results were really cool. I imagine achieving stability for a single orbiting body would be a much simpler task.
The gravitational laws are easy enough to implement and you’ll get a true to life elliptical orbit, of course elliptical orbits can be animated too should you go down that route.
