A free generative art piece — play it in your browser, no install. An interactive, physically grounded solar system rendered with three.js and WebGPU. Real ephemerides, GPU-solved asteroid belts, and eclipses that land where they actually landed.

Open the live demo Source on GitHubMost solar system viewers show you the solar system, from outside, looking in.
This one also shows you the sky — from a latitude and longitude on any solid body, at any moment in history or the future — and it finds the moments worth looking at instead of reading them from a table.
Stand in Luxor at 10:07 UTC on 2 August 2027 and the Sun is 81.8° up and completely covered, because that is where and when it will be. Ask for eclipses visible from where you are and it sweeps the ephemeris and tells you, with the duration of totality and how high the Sun will be.
