Transiting refers to the method used in astronomy to detect planets outside of our solar system by observing the periodic dimming of a star as a planet passes in front of it. This technique has been instrumental in the discovery of thousands of exoplanets and has provided valuable information about their size, orbit, and location relative to their host star. Transiting planets can yield important insights into the formation and evolution of planetary systems and are essential for studying the diversity of exoplanets in our galaxy.
