Orbit
Build an interactive solar system where planets orbit a glowing sun on elliptical paths with a twinkling star background; animate each planet at a different relative speed (Mercury fastest, Neptune slowest). Hovering a planet makes it glow and shows a small name tooltip near the cursor. Clicking a planet smoothly zooms and pans to center it and opens a bottom info panel with the planet name and a set of stat cards (diameter, mass, distance, day length, gravity, temperature) plus a fun fact. Include bottom navigation dots to jump between planets, support left/right arrow keys, and let users zoom with scroll/pinch and +/− buttons. Saturn should have visible rings. Clicking empty space or pressing Escape returns to the full system view.
