Earth-Moon Geometric Relationship
Visualizing the angular measurements between Earth's poles and the Moon's center
Scientific Visualization

Moon
This interactive visualization demonstrates the geometric relationship between Earth's rotational axis and the Moon's position in space. When you click "Draw Observation Lines", the simulation renders:
- A red line from Earth's North Pole to the Moon's center
- A green line from Earth's South Pole to the Moon's center
- The angle between these lines represents the parallax measurement
Astronomical Significance
This configuration is fundamental to:
- Lunar distance measurement using parallax methods
- Understanding Earth-Moon geometry during different lunar phases
- Celestial navigation principles
- Satellite communication angle calculations
Interactivity Guide
- Rotate: Click and drag anywhere on the visualization
- Zoom: Use mouse wheel or pinch gesture on touch devices
- Pan: Right-click and drag or two-finger drag on touchpad
- Reset: Click "Reset View" to return to default camera position
