This is a small project I've been sitting on for years now, but I'm using it as an excuse to fine-tune my TypeScript skills.
This Orbital Physics Simulation simulates gravitational interactions between celestial bodies with Newton's Law of Universal Gravitation, and is relatively consistent (I say relatively because timewarping is tricky to get right since it skips over intermediate positions and directly scales changes in time).
See this for yourself at wowtravis.com/orbital-sim, now on mobile!
