What Is Angular Distance?

Angular distance , that is, angular distance , also known as angular separation , visual distance , or visual separation , is different from two points in mathematics (especially geometry and trigonometry) and natural science (including astronomy, geology, etc.) The position of the object (ie, the third point) observes the two objects, and the angle between the straight lines that the observer points to the two objects. Angular distance (or separation) is synonymous with angle itself, but the meaning is a suggestion (usually large or unknown) of the line distance between two celestial bodies (to the star when viewed from the earth).

Because the angular distance (or separation) is the same concept as the angle, he was used the same
