Service Request Form Do You Know... What is Zenith? Zenith word has following meanings: The point on the celestial sphere that is directly above the observer The upper region of the sky The highest point above the observer's horizon attained by a celestial body The point of culmination, the peak. In general terms, the zenith is the direction pointing directly "above" a particular location; that is, it is one of two vertical directions at the location, orthogonal to a horizontal flat surface there. The concept of "above" is more specifically defined in astronomy, geophysics and related sciences as the vertical direction opposite to the net gravitational force at a given location. The opposite direction, i.e. the direction of the gravitational force is called the nadir. The term zenith also refers to the highest point reached by a celestial body during its apparent orbit around a given point of observation. This sense of the word is often used to describe the location of the Sun, but it is only technically accurate for one latitude at a time and only possible at the low latitudes. The zenith is used in the following scientific contexts: It serves as the direction of reference for measuring the zenith angle, which is the angular distance between a direction of a star and the local zenith, relative to the point for which the zenith is defined. It defines one of the axes of the horizontal coordinate system in astronomy. © 2003-2013 ConsultingLand.com — All Rights Reserved.
