Horizon view
Horizon from Cai Lun
80.1166° N, 113.6639° E · cell ZLS
- Highest horizon point
- Cai Lun: 18.6° above the horizontal, 0.88 km away at azimuth 61°.
- Farthest visible point
- 2.16 km away at azimuth 279°, 8.7° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 2,631 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is 1.4° above the smooth horizon at azimuth 254° but behind terrain: the skyline there rises to 8.9°. At 2026-10-22 13:45:01 UTC, when this page was served.
- Resolution
- Terrain resolution: about 160 m at this point and about 1.9 km at the farthest samples; nearby foreground relief is smoothed at the coarser tiers, and the model does not include boulders or other surface hazards.

Peaks on the skyline
- 61° Cai Lun, 0.88 km away, 18.6° high, 297 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.
