Horizon view
Horizon from Mersenius U
23.0135° S, 50.1179° W · cell 17KCT
- Highest horizon point
- Mersenius U: 7.7° above the horizontal, 2.84 km away at azimuth 259°.
- Farthest visible point
- 12.3 km away at azimuth 66°, 3.8° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 413 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is 1.9° above the smooth horizon at azimuth 91° but behind terrain: the skyline there rises to 4.1°. At 2026-10-22 16:15:44 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.

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.
