It allows astronomers to chart the path of stars and other celestial bodies, providing valuable data about their movement and position. Moreover, the zenith is also crucial in the field of celestial navigation.
In a scientific context, the zenith is the direction of reference for measuring the zenith angle (or zenith angular distance), the angle between a direction of interest (e.g. a star) and the local zenith - that is, the complement of the altitude angle (or elevation angle).

May 23, 2018 · zenith, in astronomy, the point in the sky directly overhead; more precisely, it is the point at which the celestial sphere [1] is intersected by an upward extension of a plumb line from the observer's location.
The zenith is the point in the sky vertically straight above the observer. It is the point where the observer's sight-line is perpendicular to the Earth's atmosphere, and hence where the smallest amount of air – termed the airmass – lies along it.
