Horizon view
Horizon from Mairan D
40.9992° N, 45.5350° W · cell 17THQ
- Highest horizon point
- Mairan D: 22.0° above the horizontal, 3.79 km away at azimuth 90°.
- Farthest visible point
- 4.74 km away at azimuth 0°, 18.5° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 3,322 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is 3.4° above the smooth horizon at azimuth 95° but behind terrain: the skyline there rises to 21.9°. At 2026-10-22 15:38:43 UTC, when this page was served.
- Resolution
- Terrain resolution: about 1.9 km, the global LOLA terrain tier of 16 pixels per degree; relief smaller than that, near or far, is smoothed, and the model does not include boulders or other surface hazards.
