Horizon view
Horizon from Billy C
16.0783° S, 49.1445° W · cell 17KDF
- Highest horizon point
- Billy C: 13.2° above the horizontal, 1.90 km away at azimuth 268°.
- Farthest visible point
- 2.84 km away at azimuth 0°, 7.4° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 1,944 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is 3.8° above the smooth horizon at azimuth 90° but behind terrain: the skyline there rises to 9.3°. At 2026-10-22 18:23:55 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.
