What are eclipse size?

Eclipse size refers to the apparent size of the moon or the sun as observed during an eclipse. In a solar eclipse, the size of the moon relative to the sun determines whether it is a total, partial, or annular eclipse. During a total eclipse, the moon completely covers the sun, while in an annular eclipse, the moon is smaller than the sun, leaving a ring of sunlight visible. The size of the eclipse can vary based on the distance of the moon and sun from Earth, as well as the observer's location.
