Exoplanets — A Comprehensive Scientific Review
The detection of planets orbiting stars beyond our Solar System — known as exoplanets — has reshaped astronomy over the past three decades. Prior to 1992, only indirect speculation existed about planets around other stars. Today, nearly 6,000 exoplanets have been confirmed through a variety of observation techniques, revealing planetary systems that challenge traditional theories of formation and habitability.
