About the Earth Curve Calculator
This calculator helps you understand the Earth's curvature, the effect of atmospheric refraction, and the visibility of distant objects.
Key Concepts:
- Earth's Radius: 6371 km (approx.)
- Atmospheric Refraction: Slight bending of light due to air layers.
- Horizon Distance: Maximum distance visible based on observer height.
- Curve Drop: How far the surface drops over distance.
