Azimuth is a term used in navigation and astronomy to describe the direction of an object in the sky relative to a fixed point on the observer’s horizon. It is typically measured in degrees from north, with east being 90 degrees, south being 180 degrees, and west being 270 degrees.

Azimuth can be thought of as the angle between the observer’s local north-south meridian (a line running from the observer’s location to the North Pole) and the vertical circle passing through the object of interest. In other words, it is the horizontal angle between true north and the point on the horizon directly below the object of interest.

Azimuth is an important concept in many fields, including astronomy, surveying, and navigation. It is used to determine the position of celestial objects in the sky, to plot the location of objects on a map or chart, and to navigate using a compass or other directional device.
