Abstract

The search for exoplanets has become one of the most dynamic and rapidly advancing fields in modern astronomy. Understanding these distant planets expands our knowledge of planetary systems and provides crucial insights into the formation and evolution of the solar system. This study compares three major exoplanet detection techniques, i.e., radial velocity, transit photometry, and gravitational microlensing. By examining their detection principles, strengths, and limitations, the study provides a theoretical foundation for selecting appropriate methods under different observational conditions. Radial velocity is particularly effective for detecting massive planets around nearby stars and measuring planetary masses; transit photometry is well-suited for identifying smaller, close-in planets; and gravitational microlensing is uniquely capable of revealing distant and low-mass planets, including those beyond the snow line. Given the complementary nature of these techniques, the paper highlights the growing importance of a multi-method approach to improve detection accuracy and broaden the scope of exoplanet discovery. This comparative framework offers practical guidance for researchers in choosing optimal detection strategies based on specific scientific goals and target characteristics.
