Why multiple scale modes?
Real planet sizes and distances cannot both fit comfortably on one screen. Use balanced mode for teaching, distance mode for spacing, and size mode for comparing planets.
Educational approximation
Planet radii and mean orbital distances are rounded from public NASA/JPL planetary data. Positions are simplified circular animations, not live ephemeris or telescope pointing data.
Real texture maps
Planet and Sun textures are local 2K assets from Solar System Scope under the Attribution 4.0 International license, based on NASA imagery and spacecraft observations.
