Exoplanet survey is a branch of astronomy that focuses on the discovery and study of planets outside of our solar system. Scientists use a variety of methods, such as the transit method and radial velocity method, to detect these exoplanets. The goal of exoplanet surveys is to better understand the diversity of planetary systems in our galaxy and potentially identify planets that could support life. This field of research has grown rapidly in recent years with the development of advanced telescopes and technology.
