What measurement defines the angular separation between the Sun and the point directly overhead (the zenith)?
Answer
Zenith distance
Zenith distance is the angular separation between the Sun and the zenith, which is the point directly overhead. When this value is smallest (closest to zero), the Sun is highest in the sky.
