Understanding Angular Distance Calculation in Astronomy and Navigation

Learn how angular distance is calculated between celestial objects using tools like sextants and its significance in navigation.

36 views

Angular distance is calculated by measuring the angle between two points from a central observation point. This angle is typically expressed in degrees, minutes, or seconds. For celestial objects, it can be determined using instruments like a sextant or more advanced astronomical tools, which measure the angle between the objects and a reference point, such as the horizon. This method is essential in astronomy and navigation to locate and track objects efficiently.
