Library/framework for a school physics project?

Question

C++ / C#

Hello. It is required to write a simulation of the motion of the planets (the N-body problem). Question: what is the best way to do this? Are there alternatives to Unity? I would like to write everything with code without a GUI editor (I don’t like these editors :))
In fact, we need a library / framework with the ability to draw graphics and the presence of a physical engine (for example, the same box2d)
Thanks in advance
Preferred languages ​​(arranged in descending order) : js, python, c#, c++.

DirectX/OpenGL ))
There will be no editor at all.
Well, so - PixiJS, pygame, all sorts of lobgdx, SDL ...
For the movement of the planets, the physics engine will not help you much, IMHO. Well, or it will introduce a non-sour error.
