Atlas26 – Real-time 3D Solar System Simulation with Three.js

Atlas26 is a real-time 3D solar system simulation built using Three.js and Next.js.

It allows users to explore space interactively, with time-driven orbital mechanics powering planets, moons, comets, and minor bodies.

Key features:

  • Kepler-based orbital motion for planets and moons

  • Real-time satellite tracking (ISS & Hubble) using SGP4

  • Asteroid Belt and Kuiper Belt simulations

  • Dynamic time controls (speed up, slow down, pause)

  • Interactive camera navigation for free exploration

  • Device-aware performance optimization

I’d love to hear feedback from the community.

Your project is very cool.
but simulation is wrong.
dark part and light of the moon exchanged.
also I think mapping direction of the Earth must change

Thank you very much for your feedback David. And thanks for highlighting the issues. I will definitely look into it and push a fix on Github soon. Its basically a v1 of Atlas. I was working on it for a past few months and now i decided to make it live and get feedback on what to fix and what features to add.

let me know if you fix that problem.
