The whole Solar System and every tracked satellite, live in the browser

In plain words

This web application displays the entire solar system and all tracked satellites in real-time within a browser. It visualizes the positions and movements of planets, moons, and orbital objects as they exist at any given moment. The tool is designed for space enthusiasts, educators, and anyone interested in understanding the current state and locations of celestial bodies and human-made satellites in orbit around Earth and the sun.

  Hello HN! Sharing a recent side project of mine, the Atlas of Space, that I built out to explore the Solar System. As a long-time space nerd, I realized recently that I didn't have a good intuition on the scale, speed, and relative orientation of the celestial bodies around us. So over the break I built out a kind of spatial Wikipedia to click around and learn about planets, moons, asteroids, and other bodies orbiting the Sun. The physics is all simulated in the browser using simple Newtonian mechanics. There's a lot left to do from here, including modeling objects in non-Keplerian orbits…
