Horizon view
Horizon from Riemann
39.3804° N, 87.1776° E · cell 34SEH
- Highest horizon point
- Riemann B: 2.5° above the horizontal, 61.6 km away at azimuth 322°.
- Farthest visible point
- 91.0 km away at azimuth 108°, 0.7° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 2,123 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is above the local horizon: 31.4° high at azimuth 238°, 29.7° above the skyline there. At 2026-10-22 11:05:57 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.
