Angular size refers to how large an object appears from a particular point of view, measured in degrees. Linear size is the actual physical size of the object measured in standard units (meters, feet, etc.). Understanding both sizes helps in translating how large an object appears to its real-world dimensions, critical for applications in astronomy and physics.
