Transit Light Curve

A transit light curve is a graph showing how a star's brightness changes when a planet passes in front of it from our perspective. As the planet moves across the star, it blocks some of the star's light, causing a slight dip in brightness. By measuring these dips over time, astronomers can learn about the planet's size, orbit, and sometimes its atmosphere. The shape and depth of the curve help scientists understand the characteristics of both the star and the planet, making transits a key tool in exoplanet research.
