👉 Compassability is a concept in physics that refers to whether or not an object can be accurately and precisely located on a given line of sight. It involves the ability to measure the angle between two lines, such as the horizon or the celestial sphere, with a precision that allows for accurate measurements at any distance from the observer. Compassability is fundamental in navigation and astronomy, where it plays a crucial role in determining the position of an object relative to another, such as a planet. It is
