Flyby

A flyby is a close encounter with a celestial object, such as a planet, moon, asteroid, or comet, during which a spacecraft observes and collects data without entering orbit or landing. It's a mission strategy focused on gathering information rapidly. The term can also be applied metaphorically to describe a quick visit or observation, emphasizing the brief and transient nature of the encounter. Flybys are often used as reconnaissance missions, allowing scientists to study objects before committing to more complex and resource-intensive orbital or landing missions. The advantage of a flyby mission is cost-effectiveness and the ability to visit multiple targets.
