What is Angular Distance in Astronomy and How to Find It?

When you look at the stars and see the shape of a triangle or two stars that seem to be smiling at you, chances are they are not actually triangular or even happy. Rather, they just appear that way because of the angular distance phenomenon. The angular distance is also known as visual angular distance or apparent angular distance. It is a unit used to measure the apparent separation between two different objects in the same field of view. In other words, it measures how far apart two objects appear when viewed from a specific point (e.g., Earth). This article will help you understand the concept of Angular Distance and its types with examples and illustrations.
