The point in the heavens directly overhead to a man standing or a growing cabbage. A man in bed or a cabbage in the pot is not considered as having a zenith, though from this view of the matter there was once a considerably dissent among the learned, some holding that the posture of the body was immaterial. These were called Horizontalists, their opponents, Verticalists. The Horizontalist heresy was finally extinguished by Xanobus, the philosopher-king of Abara, a zealous Verticalist. Entering an assembly of philosophers who were debating the matter, he cast a severed human head at the feet of his opponents and asked them to determine its zenith, explaining that its body was hanging by the heels outside. Observing that it was the head of their leader, the Horizontalists hastened to profess themselves converted to whatever opinion the Crown might be pleased to hold, and Horizontalism took its place among _fides defuncti_.

That point in the visible celestial hemisphere which is vertical to the spectator; the point of the heavens directly overhead; -- opposed to nadir.

hence, figuratively, the point of culmination; the greatest height; the height of success or prosperity.

The point in the celestial sphere directly overhead; opposite the nadir. the zenith and nadir are the poles of the horizon.

The point on the Celestial Sphere which is directly overhead. A line from the center of the Earth through the observer will go through the zenith. The point opposite the zenith, directly below the observer, is the nadir.

The point in the celestial sphere directly above the head of an observer on Earth.

The point in celestial sphere directly overhead from an observer.

the point on the celestial sphere directly above the observer

The point in the sky which is directly overhead.

in general, the point directly overhead on the celestial sphere. The astronomical zenith is the extension to infinity of a plumb line. The geocentric zenith is defined by the line from the centre of the Earth through the observer. The geodetic zenith is the normal to the geodetic ellipsoid at the observer's location. (See deflection of the vertical.)

That point, on any given observer's celestial sphere, that lies directly above him; the point that is elevated 90° from all points on a given observer's astronomical horizon. Diametrically opposite the zenith is the observer's nadir.

The part of the celestial sphere which is exactly overhead

Point on the celestial sphere vertically above a given position or observer.

Point of the celestial sphere vertically above (highest point) any place or observer.

the point above the observer that is directly opposite the nadir on the imaginary sphere against which celestial bodies appear to be projected

The point on the meridian directly above an observer.

The highest point in the heavens, vertically above the observer and directly opposite the nadir, the lowest point.

(Z). Point on the celestial sphere directly over the observer's head.

highest point in the sky directly above the observer's head

The point in the sky directly above the observer. The top of the sky.

A point on the celestial sphere that is directly above an observer.

The point in the sky directly overhead. The horizon is 90° away from the zenith in all directions.

As far from a Horizon as can be -- that is, the most recent Time Step Transitioned Variable maintains pointers to the Mode Transition Variable at both the Horizon and the Zenith.

This is the point directly overhead. It is 90° from the horizon. The position of the celestial pole with respect to this point vary according to where on the Earth you make your observations. From the geographic North pole, the North celestial pole will be at the zenith. The angular distance between the zenith and the celestial pole is given by the 90° minus your latitude. The nadir is the point exactly opposite the zenith on the celestial sphere.

The point on the celestial sphere directly above an observer, or the highest point in the sky reached by a celestial body.

The point of the celestial sphere which is directly overhead.

A point directly overhead from an observer.

The point in the sky directly over the observer's head, and 90° from the horizon in every direction.

the point on the celestial sphere directly over the head of an observer.

The highest or culminating point.

The point directly overhead, or highest point. Also the mid-heaven (MC).

The point which is elevated 90 degrees from all points on a given observer's astronomical horizon. The point on any given observer's celestial sphere that lies directly above him. The opposite of nadir.

An observer's zenith is the point directly overhead.

In broad terms, the zenith is the direction pointing directly above a particular location (perpendicular, orthogonal). Since the concept of being above is itself somewhat vague, scientists define the zenith in more rigorous terms. Specifically, in astronomy, geophysics and related sciences (e.g., meteorology), the zenith at a given point is the local vertical direction pointing away from direction of the force of gravity at that location.
