TESIGN TAKE

Publishing an accuracy table and a verify script is what separates this from solar system apps that only look right.

AT A GLANCE

WHY IT MATTERS

Space apps usually make you choose between accuracy and immersion; this one puts both in a web page. The README's accuracy table lists planet positions within 0.0007°–0.074° of NASA JPL Horizons, the Moon at 0.12° and 21 moons within 0.22° after ten days, and `npm run verify` re-checks against Horizons live. It runs at true 1:1 km scale from the Sun to the 100,000 AU Oort Cloud, ships about 200 kB of gzipped JS and supports phone touch.

BUILD FROM THIS

The ephemeris layer is pure functions testable in Node, so it can feed your own astronomy visualisation or lesson material, and the roadmap's guided tours and courses are open for education content. MIT allows commercial use; the textures carry their own CC-BY-4.0 and similar attribution terms.

WHO IT'S FOR

Teachers and students: land on the Moon and look up at Earth, get a feel for scale
Astronomy enthusiasts: today's real planet positions, 28 TNOs and 4 comets
Web 3D developers: floating-origin rendering and a logarithmic depth buffer at 1:1 km scale
