Physically Accurate Orbit Simulation

Hello Unity users! I'm working at an open source code for simulating elliptical orbits in Unity, I've made a few lessons on YouTube, and I was thinking that if anybody is interested in suggesting any changes and constructively criticizing the work I'm doing they're welcome
The functions I've implemented so far are the following:

• Making an object follow the elliptical path
• Making the speed change according to the position on the path, and depending on G and the mass of the object
• Visualizing the ellipse using a LineRenderer
• Visualizing the position of Apoapsis and Periapsis on the ellipse

I'm now working on rotating the orbit along the three axes and calculating the components of the speed, in order to, sooner or later, add a KSPish maneuver system.

Let me know what you think:

(In the first couple of videos I was actually kind of nervous lol)

Oh, and a little (Off topic) treat for the intellectuals here:

 

nice this really helped also have you done a maneuver system?

 

Nope, but I'm working on something similar to that
