Horizon view
Horizon from Mersenius
21.4928° S, 49.3362° W · cell 17KDU
- Highest horizon point
- An unnamed point: 3.0° above the horizontal, 38.9 km away at azimuth 19°.
- Farthest visible point
- 48.3 km away at azimuth 141°, 1.3° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 1,629 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is 0.1° above the smooth horizon at azimuth 91° but behind terrain: the skyline there rises to 2.0°. At 2026-10-22 11:05:42 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.
Vertical scale exaggerated 10x (horizontal 4 px per degree). Eye 2 m above the ground.Scroll sideways to turn; the middle faces 19°.

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.
