Artifacts
Interactive pages made with Claude: models, maps and tools, each shown with a note on what it does, where its data come from, and its limits. Newest first. They are searchable alongside the rest of the site (search only the artifacts).
Heliocenter: A 3D Model of the Solar System
An interactive 3D model of the solar system that places the planets, dwarf planets, selected asteroids, Halley's Comet and the two Voyager probes on any date, using JPL orbital elements for 3000 BCE to 3000 CE or a Newtonian n-body integration for 100,000 years either way.
The Solar Neighborhood: Stars Within 10 Parsecs
An interactive 3D map of the star systems within about 10 parsecs (32.6 light-years) of the Sun, with each star moved along its measured space velocity so the neighborhood can be run 100,000 years forward or back.
