Basically this formula relates the angular size of an object (how big the object appears to an observer), the actual physical size d of the object, and the distance D from the observer to the object.
So let's say i want to find the physical size of Betelgeuse. As a scientist figuring this out, how would you find theta, or angular size of a star 600 light years away, and what is the angular size actually measuring?
