Horizon view
Horizon from Alter W
20.3821° N, 109.4090° W · cell 9QHQ
- Highest horizon point
- Alter W: 7.4° above the horizontal, 22.7 km away at azimuth 231°.
- Farthest visible point
- 27.5 km away at azimuth 7°, 4.0° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 271 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is below the horizon: 55.4° under it at azimuth 60°. At 2026-10-22 11:05:38 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.
