1. **Earth's axial tilt**: Earth is tilted at approximately 23.5° relative to its orbital plane
2. **During Antarctic summer**: The South Pole is tilted toward the sun
3. **Result**: Locations within the Antarctic Circle (66.5°S and further south) experience continuous daylight, with the sun making a complete circle above the horizon over 24 hours
