A 2D scatter-plot model of the solar system: monthly positions of the eight planets, Jan 1900 → Dec 2100. Heliocentric ecliptic view, distances in AU, positions from Astropy's built-in ephemeris. Use the timeline to scrub or play through two centuries of orbits.
Drag the slider or press ←/→ to step one month, Space to play/pause. Hover a planet for its exact distance from the Sun. Planet dots sit on their current-distance orbit guide. Data generated with astropy — one frame per month, all 2,412 frames embedded in this file.
