Horizon view
Horizon from Mersenius J
20.9905° S, 52.9151° W · cell 16KJQ
- Highest horizon point
- Mersenius J: 15.0° above the horizontal, 0.95 km away at azimuth 261°.
- Farthest visible point
- 3.79 km away at azimuth 71°, 6.6° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 1,509 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is 0.6° above the smooth horizon at azimuth 91° but behind terrain: the skyline there rises to 7.6°. At 2026-10-22 19:05:11 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
- 261° Mersenius J, 0.95 km away, 15.0° high, 256 m above the ground here
- 93° Mersenius J, 3.79 km away, 7.6° high, 508 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.
