Really cool project. I'm curious what was the most surprising thing you learned while building this that changed your own understanding of how gravity or orbits work?
What I did is a straight forward model, yet it's still complex. The way to figure it out how it works by observation from earth without tools we have now it's insane. How Copernicus, Kepler, Galilei, Newton, Hubble, Einstein figure it out it just amazing. Science deserves all the kudos!
