Occultation

An occultation is an event that occurs when one object is hidden by another object that passes between it and the observer.  A planet, for example, can pass in front of a star.  Some occultations are eclipses. The word is often used in astronomy. It can also be used in a non-astronomical sense to describe when an object in the foreground occults (covers up) objects in the background.
