Exoplanets are planets that exist outside our solar system, orbiting stars other than the Sun. They are crucial in understanding planetary systems and the potential for life beyond Earth, and their study involves various methods like observing transit timing variations, analyzing tidal heating effects, and mapping eclipses to reveal their characteristics. Exoplanets also interact dynamically with other celestial bodies, affecting their orbits and environments, which are essential for habitability assessments.
