Larawag demo
An editable star system drawn by the Larawag library. Edit the fields below and the scene updates. Drag to rotate, scroll to zoom, click a planet or its label to follow it (Esc releases).
Derived values come from the library: Kepler's third law for orbit size and speed, insolation and equilibrium temperature (Bond albedo 0.3) from the star, and colour from a blackbody at the star's temperature. Distances are compressed unless true scale is on. Planet class is only a guess from size.
