Transiting planets refer to exoplanets that pass in front of (transit) their host star, as seen from Earth. This phenomenon causes a temporary decrease in the star's brightness, which can be detected and studied by astronomers. By observing these transits, researchers can gather valuable information about the properties of the exoplanet, such as its size, composition, and atmosphere. Transiting planets have been instrumental in expanding our understanding of the diversity of planetary systems beyond our own solar system.
