Occultation - English Definition & Meaning

Definition

Occultation happens when one celestial object passes in front of another, hiding it from view. 🔭 It’s similar to an eclipse, but it’s often used for more general cases where one object obscures another. Think of it as a cosmic cover-up. 🕵️ Unlike an eclipse, the objects don't necessarily have to be a star and a planet or moon. Occultation can involve asteroids, comets, or other celestial bodies. Observing occultations helps astronomers learn about the sizes and shapes of distant objects.
