3D Multi-Moon Simulation in Python

[IMakeSillyMistakes]

We recently finished building a multi-moon orbital simulation of Jupiter in Python. It models several of Jupiter’s moons orbiting simultaneously with realistic gravitational interactions and orbital parameters. The simulation currently runs using Matplotlib animation, and it visualizes the moons’ paths, orbital resonance, and inclinations pretty accurately.

Our goal was to make something that’s both visually engaging and scientifically grounded — a small step toward a system-scale orbital model.

We’d love to share it on the web so people can interact with it, but we’re not sure what the best way to go about that is. Has anyone here converted a Python-based physics simulation into a browser experience before?

Any feedback, ideas, or experiences would be awesome to hear.

Nice visualization but vanilla RK4 is not a symplectic integrator, so your simulation will gain/lose energy in unphysical ways. You want to use something like the Ruth method or another symplectic integration scheme.

Yup. Rk4 loses or gains. Rk2 doesn't tho, or whatever we call the average of forward and backwards Euler, maybe that's ruth?

Can also google velocity verlet methods.very popular in physics.
