Horizon view
Horizon from Mersenius R
19.3957° S, 47.6842° W · cell 17KFB
- Highest horizon point
- Mersenius R: 16.9° above the horizontal, 0.95 km away at azimuth 11°.
- Farthest visible point
- 2.84 km away at azimuth 53°, 16.1° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 1,198 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is 4.5° above the smooth horizon at azimuth 90° but behind terrain: the skyline there rises to 10.7°. At 2026-10-22 17:09:00 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.

Peaks on the skyline
- 11° Mersenius R, 0.95 km away, 16.9° high, 289 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.
