Earth sways in the lunar sky
Lunar libration · view from the Moon
From 0° latitude, 75° east on the Moon, Earth sways against the fixed grid: this is lunar libration viewed from the Moon. At one day per second, watch about a month from 24 October 2026. Tracking is off; gestures remain free. The ground is illustrative. The path varies and need not form a closed figure eight.
Why explore it?
The Moon’s orbit and orientation change Earth’s direction despite synchronous rotation. Compare its position against the local grid; changing phase and apparent diameter are separate phenomena.
