Phaenon

Advance the nights, or watch them run. Mark every light that moved. The slowest is easy to mistake for a star. Left and right change the night. Up and down select. Space marks. W watches.

Represented: apparent motion of the five naked-eye wanderers along one ecliptic. Simplified: each night is thirty days, so Phainon’s slowness can be compared in a sitting. Distances are composed.
