I need to scale my solar system model and it's not working. I'm making an augmented reality app that shows a sample solar system rotating. It works great! (Thanks to this $7 program https://assetstore.unity.com/packages/tools/physics/gravity-and-orbits-solar-system-105300 . The Unity engine is free). However I need to scale my solar system to support the AR functionality. I have a planet in the middle and smaller planets rotating in a semi-stable orbit. When I scale everything down by 50% (the objects, distances, mass, initial velocity) it's no longer a stable orbit. They crash into the center planet within one orbit. Should this work this way? Would solar system where everything is exactly 50% smaller still produce stable orbits? Am I missing something with regards to scaling my physical model or should I not expect things to scale linearly? Thanks!
