Horizon view
Horizon from Challis
79.5799° N, 9.0856° E · cell 24XFG
- Highest horizon point
- Challis: 3.3° above the horizontal, 24.6 km away at azimuth 206°.
- Farthest visible point
- 63.6 km away at azimuth 16°, 0.1° from the horizontal.
- Observer
- Eye 2 m above the ground, which is 1,272 m below the 1,737.4 km reference sphere.
- Sun at the rendered time
- The Sun is above the local horizon: 7.5° high at azimuth 148°, 4.6° above the skyline there. At 2026-10-22 11:05:20 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.
