x̄ -> Solar system visualisation

Your solar system visualization app should incorporate Earth’s rotation on its axis, Earth’s revolution around the Sun, and the Moon’s orbit around Earth in a scientifically accurate yet visually engaging way. Here’s how you can structure these motions in your app:

---

1. Earth's Rotation on Its Axis 🌍🔄

• The Earth rotates counterclockwise (west to east) when viewed from above the North Pole.
• It completes one full rotation in 24 hours, causing day and night cycles.
• You can animate this in Three.js (or a 2D canvas) by rotating the Earth sprite/element around its axis continuously.
• Optionally, you can add a tilt of 23.5°, affecting seasons when combined with revolution.

2. Earth's Revolution Around the Sun ☀️🌀

• Earth orbits the Sun in an elliptical path (though often shown circular for simplicity).
• One full revolution takes 365.25 days, which causes seasons when combined with axial tilt.
• The Earth’s movement should be programmed as a smooth transition along its orbit, maintaining the correct tilt direction throughout.

3. Moon’s Orbit Around Earth 🌙🔁

• The Moon revolves counterclockwise around Earth in 27.3 days.
• It always shows the same face toward Earth due to synchronous rotation.
• The Moon’s orbit should be elliptical and slightly tilted (5° relative to Earth’s orbit around the Sun).
• Optional: Simulating lunar phases based on Sun-Earth-Moon positioning.
