is there an easy way to simulate custom star system?

I think part of software development will hard and expensive part. A web software tester works closely with the developers to test the software for usability, compatibility, and robustness. The software development companies use testing methods such as functional, structural, and logical testing, code coverage, and automated testing. That is why I prefer https://mlsdev.com/services/dedicated-development-team

I have not yet found one that is editable. I want to add planets of a certain size on a certain orbit .
Create and destroy on an unimaginable scale... with a space simulator that merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. .
It's in early access but that's as far as you can get with having software installed on PC.

Try Orbiter space simulator, start at orbiterwiki.org. It will have a link to the download and for add-ons. It is a free simulator written by Dr Martin Schweiger and the add-ons by a group of developer hobbyists, providing real world physics, orbital mechanics and aerodynamics. The stock sim comes with the real solar system, but you could archive the bodies and develop your own planets and moons, others have done that already. Check it out. The folks at Orbiter-forum.com are from all over the world and are very helpful to get you up and running with sim play as well as development. Once you develop new bodies, spacecraft, whatever, you could upload them to the orbiter-hangar so others can enjoy your work. Let me know what you think. Just be patient, they do this in their spare time, it’s their hobby and who knows, it could be yours, as well.
