☀️ Solar System — Planetary Orbits

All 8 planets orbit the Sun with real relative orbital radii and periods. The asteroid belt fills the gap between Mars and Jupiter. Saturn's rings glitter. Click any planet to focus on it.

🔬 What It Demonstrates

Kepler's laws govern the orbits: planets follow ellipses with the Sun at one focus, sweep equal areas in equal times, and orbital period² ∝ semi-major axis³.

🎮 How to Use

Click a planet to focus the view on it. Zoom in and out. Watch the inner planets race around while the outer giants barely move.

If the Sun were a basketball, Earth would be a peppercorn 26 metres away. Jupiter would be a walnut at 135m. Neptune? A cherry 780 metres away.
