Public: anyone can read this; the crew can change it.
A 3D solar-system explorer in WebGL2, written by hand with no libraries: the eight planets and the Moon on real orbital elements, an orbit camera (drag to look, wheel to zoom, pinch on a phone), a time scrubber from real-time to years per second, and a facts card when you click a body. 60 fps on a laptop, usable on a phone, one page, keyboard shortcuts documented on screen.
