Celestial Coordinate System. azimuth. Azimuth is the number of degrees clockwise from due north (usually) to the object’s vertical circle (i.e., a great circle through the object and the zenith). overhead point to make 90 degrees. [1] It was reduced to "samt" ("direction") and miswritten as "senit"/"cenit", the "m" being misread as "ni". altitude. The NASA Orbital Debris Observatory and the Large Zenith Telescope are both zenith telescopes since the use of liquid mirrors meant these telescopes could only point straight up. For visible objects, it is an angle between 0° and 90°. A zenith telescope is a type of telescope designed to point straight up at or near the zenith, and used for precision measurement of star positions, to simplify telescope construction, or both.

The astronomical meridian is also determined by the zenith, and is defined as a circle on the celestial sphere that passes through the zenith, nadir, and the celestial poles. and its zenith distance is (90° - the altitude) = 90° - 51° = 39°. How do you Find Free eBooks On-line to Download? Celestial Equator. The zenith angle is similar to the elevation angle but it is measured from the vertical rather than from the horizontal, thus making the zenith angle = 90° - elevation. is the angle of the object around the horizon, usually measured from true north and increasing eastward. How to use zenith in a sentence. The term zenith sometimes means the highest point, way, or level reached by a celestial body on its daily apparent path around a given point of observation.
