A transiting exoplanet is a planet that orbits a star and passes in front of it from our viewpoint on Earth. This transit causes a temporary dimming of the star's light, which can be measured by telescopes. By analyzing this light curve, scientists can determine the planet's size, orbit, and distance from its star. The study of transiting exoplanets has become crucial in the search for potentially habitable worlds. Missions like Kepler and TESS have discovered thousands of these planets, expanding our understanding of planetary systems beyond our own.
