This project was built with the assistance of ChatGPT4, through much trial and error.

The data comes from Solar System OpenData (view github).

Simulation Accuracy

Space is big, so I had to make several tweaks for aesthetic reasons.

• The orbital periods for planets and moons are sped up significantly. At the default speed, Earth will complete a full orbit in 365.256 seconds (1 day == 1 second). The other moons and planets orbit accurately in relation to that scale.
• The sizes of planets are not to scale, but are sized proportionately within a minimum and maximum range
• The orbital distances are evenly spaced for visual reasons. Plans and moons are accuratley ordered by their Semimajor axis, but the actual diameter of the orbit is not to scale.
• Not all moons and bodies are shown. All of the inner moons are shown (Earth's Luna, and Mars' Phobos and Deimos). Of the outer planet moons, only moons with a mean radius of 80km or above are shown.
• The colors are made up.
