Definitions for **"Angular distance"**

The distance between two objects, measured in terms of the angle between them at the point of observation.

the angular separation between two objects as perceived by an observer; "he recorded angular distances between the stars"

Angular distance is the measure of an arc (a segment of the circumference of a circle). Angular distance measures the proportion of a circle that the arc in question consists of. Angular distance is expressed in degrees, radians, arc minutes (one-sixtieth of a degree), or arc seconds (one-sixtieth of a minute). For example, latitude is the angular distance north or south of the equator measured in degrees, and longitude is the angular distance east or west of the prime meridian (which goes through Greenwich, England), measured in degrees.
