Exoplanet research focuses on the study of planets outside our solar system, known as exoplanets. Scientists aim to discover their characteristics, such as size, composition, and distance from their host stars. This research helps us understand the diversity of planetary systems and the potential for life beyond Earth. Methods used in exoplanet research include the transit method, where astronomers observe the dimming of a star's light as a planet passes in front of it, and the radial velocity method, which detects wobbles in a star's position due to gravitational pulls from orbiting planets. These techniques have led to the discovery of thousands of exoplanets.
