Horizon view
Horizon from Mersenius C
19.7636° S, 45.9909° W · cell 17KHB
- Highest horizon point
- Mersenius C: 24.5° above the horizontal, 5.69 km away at azimuth 236°.
- Farthest visible point
- 6.63 km away at azimuth 38°, 21.1° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 3,236 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is 6.7° above the smooth horizon at azimuth 89° but behind terrain: the skyline there rises to 18.1°. At 2026-10-22 18:21:23 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.

- 236° Mersenius C, 5.69 km away, 24.5° high, 2,606 m above the ground here
- 25° Mersenius C, 5.69 km away, 22.2° high, 2,326 m above the ground here
A ray every 0.5 degrees out to 200 km across the NASA LRO LOLA terrain, the curvature of the Moon included; each peak is named only when an IAU feature's mapped footprint lies over the point that forms it. Smooth terrain between samples, no boulders.
