Occultation is an astronomical event that occurs when one celestial body passes in front of another, temporarily blocking it from view. This phenomenon can involve various objects, such as stars, planets, or moons, and is often used by astronomers to study the characteristics of the obscured body, including its size and atmosphere. A well-known example of occultation is when the Moon passes in front of a star, causing the star to disappear and then reappear as the Moon moves. Observing these events can provide valuable data about both the occulting and the occulted objects, enhancing our understanding of the universe.
