2. A close approach of a spacecraft to a planetary body for the purpose of gathering scientific information; it can also describe a short, casual visit by a person; a flying technique involving a low-altitude pass over a target location
3. The passage of a space vehicle near a planetary surface to conduct research or collect images; this term may also denote a quick social visit; or a low-flying maneuver performed by an aircraft for inspection or display

Etymology: The term "flybys" refers to a space mission in which a spacecraft approaches a celestial body closely enough to gather data without entering orbit. This strategic maneuver has become a hallmark of space exploration, allowing scientists to study planets, moons, and other celestial objects while conserving fuel and resources. The concept of a flyby has its roots in the early days of space exploration, particularly during the mid-20th century when scientists began to explore the possibilities of interplanetary travel. The word itself is a compound of "fly" and "by," where "fly" traces back to Old English "flēogan," meaning to soar through the air, and "by," which comes from the Old English "bū," signifying near or in proximity to. The combination of these two elements effectively conveys the essence of the action: flying close to something. The usage of "flyby" in the context of space missions likely began to gain traction in the 1960s, coinciding with significant missions such as the Mariner program, which conducted flybys of Mars and Venus. In its journey into common usage, the term has also evolved to encompass not only the technical aspects of space missions but also a broader metaphorical application. For instance, "flybys" can refer to brief encounters or quick visits in everyday life, demonstrating the word's flexibility and adaptability. This semantic shift mirrors the word's trajectory from a specific scientific context to a more generalized use, reflecting the influence of space exploration on popular culture and language. As the field of space exploration continues to advance, the term "flybys" remains relevant, embodying the spirit of discovery and human curiosity about the universe. It serves as a reminder of the incredible achievements of scientists and engineers who push the boundaries of our understanding of the cosmos, capturing the imagination of generations.
