A browser map tracks 526,000 asteroids in real-time 3D

You can now fly through a real-time 3D map of 526,000 asteroids and every tracked satellite straight from your browser.

A new project shared on Hacker News renders our Solar System in interactive 3D. The web app loads half a million space rocks alongside active satellites, giving you flight controls to explore the map in real time.

Why it matters: Rendering this much orbital data usually takes heavy desktop software or custom graphics setups. Running 526,000 live objects directly in a browser turns complex space tracking into an instant interactive tool.

Know this: You steer like a space flight simulator. Use WASD to fly, Shift to speed up, and drag your mouse to rotate the camera. Double-click any planet or asteroid to fly straight to it, or click group names to highlight whole asteroid families at once.

It is easily the best way to spend five minutes realizing how crowded our orbit actually is.
