Zenith refers to an imaginary point directly "above" a particular location, on the imaginary
celestial sphere. "Above" means in the vertical direction opposite to the apparent
gravitational force at that location. The opposite direction, i.e. the direction in which
gravity pulls, is toward the
nadir. The zenith is the "highest" point on the celestial sphere (meaning it is the farthest up from the gravitational force). Zenith is sometimes used as a given name, most commonly for males. Its meaning, "highest point," evokes success and power.
