What is the term for the partial or total blocking of one object in space by another?

The term for the partial or total blocking of one object in space by another is best defined as an eclipse. This phenomenon occurs when one celestial body moves into the shadow of another celestial body or when an object is obscured by another overlapping object. For example, a solar eclipse happens when the Moon passes between the Earth and the Sun, momentarily blocking the Sun's light. Similarly, a lunar eclipse occurs when the Earth comes between the Sun and the Moon, casting a shadow on the Moon.

The other terms listed serve different purposes: "occlusion" usually refers to the act of obstructing or blocking in a more general sense, often used in various fields like medicine or optics; "intervention" signifies involvement or action to improve a situation; and "coronation" pertains to the ceremony of crowning a monarch. Thus, while they are relevant in their own contexts, they do not accurately describe the astronomical event of one object blocking another in space as an eclipse does.
